9 Detailed Description
9.1 Overview
SGx524 is a fixed-frequency pulse-width-modulation (PWM) voltage-regulator control circuit. The regulator
operates at a fixed frequency that is programmed by one timing resistor, RT, and one timing capacitor, CT. RT
establishes a constant charging current for CT. This results in a linear voltage ramp at CT, which is fed to the
comparator, providing linear control of the output pulse duration (width) by the error amplifier.
The SGx524 contains an onboard 5-V regulator that serves as a reference, as well as supplying the SGx524
internal regulator control circuitry. The internal reference voltage is divided externally by a resistor ladder network
to provide a reference within the common-mode range of the error amplifier as shown in Figure 11, or an external
reference can be used.
The output is sensed by a second resistor divider network and the error signal is amplified. This voltage is then
compared to the linear voltage ramp at CT. The resulting modulated pulse out of the high-gain comparator then is
steered to the appropriate output pass transistor (Q1 or Q2) by the pulse-steering flip-flop, which is
synchronously toggled by the oscillator output. The oscillator output pulse also serves as a blanking pulse to
ensure both outputs are never on simultaneously during the transition times. The duration of the blanking pulse is
controlled by the value of CT.
The outputs may be applied in a push-pull configuration in which their frequency is one-half that of the base
oscillator, or paralleled for single-ended applications in which the frequency is equal to that of the oscillator. The
output of the error amplifier shares a common input to the comparator with the current-limiting and shut-down
circuitry and can be overridden by signals from either of these inputs. This common point is pinned out externally
via the COMP pin, which can be employed to either control the gain of the error amplifier or to compensate it. In
addition, the COMP pin can be used to provide additional control to the regulator.

9.3 Feature Description
9.3.1 Blanking
The output pulse of the oscillator is used as a blanking pulse at the output. This pulse duration is controlled by
the value of CTas shown in Figure 2. If small values of CTare required, the oscillator output pulse duration can
be maintained by applying a shunt capacitance from OSC OUT to ground.
9.3.2 Error Amplifier
The error amplifier is a differential-input transconductance amplifier. The output is available for DC gain control or
AC phase compensation. The compensation node (COMP) is a high-impedance node (RL=5MΩ). The gain of
the amplifier is AV = (0.002 Ω–1)RLand easily can be reduced from a nominal 10,000 by an external shunt
resistance from COMP to ground. Refer to Figure 1 for data.
9.3.3 Compensation
COMP, as previously discussed, is made available for compensation. Since most output filters introduce one or
more additional poles at frequencies below 200 Hz, which is the pole of the uncompensated amplifier,
introduction of a zero to cancel one of the output filter poles is desirable. This can be accomplished best with a
series RC circuit from COMP to ground in the range of 50 kΩand 0.001 μF. Other frequencies can be canceled
by use of the formula f ≈1/RC.
9.3.4 Output Circuitry
SGx524 contains two identical npn transistors, the collectors and emitters of which are uncommitted. Each
transistor has antisaturation circuitry that limits the current through that transistor to a maximum of 100 mA for
fast response.
9.3.5 Current Limiting
A current-limiting sense amplifier is provided in the SGx524 device. The current-limiting sense amplifier exhibits a
threshold of 200 mV ±25 mV and must be applied in the ground line since the voltage range of the inputs is
limited to 1 V to –1 V. Caution should be taken to ensure the –1-V limit is not exceeded by either input,
otherwise, damage to the device may result.
Foldback current limiting can be provided with the network shown in Figure 5. The current-limit schematic is
shown in Figure 6.

9.4 Device Functional Modes
9.4.1 Synchronous Operation
When an external clock is desired, a clock pulse of approximately 3 V can be applied directly to the oscillator
output terminal. The impedance to ground at this point is approximately 2 kΩ. In this configuration, RTCTmust be
selected for a clock period slightly greater than that of the external clock.
If two or more SGx524 regulators are operated synchronously, all oscillator output terminals must be tied
together. The oscillator programmed for the minimum clock period is the master from which all the other
SGx524s operate. In this application, the CTRTvalues of the slaved regulators must be set for a period
approximately 10% longer than that of the master regulator. In addition, CT (master) = 2 CT(slave) to ensure that
the master output pulse, which occurs first, has a longer pulse duration and, subsequently, resets the slave
regulators.
9.4.2 Shutdown Circuitry
COMP also can be employed to introduce external control of the SGx524. Any circuit that can sink 200 μA can
pull the compensation terminal to ground and, thus, disable the SGx524.
In addition to constant-current limiting, CURR LIM+ and CURR LIM– also can be used in transformer-coupled
circuits to sense primary current and shorten an output pulse should transformer saturation occur. CURR LIM–
also can be grounded to convert CURR LIM+ into an additional shutdown terminal.

10 Application and Implementation
NOTE
Information in the following applications sections is not part of the TI component
specification, and TI does not warrant its accuracy or completeness. TI’s customers are
responsible for determining suitability of components for their purposes. Customers should
validate and test their design implementation to confirm system functionality.
10.1 Application Information
There are a wide variety of output configurations possible when considering the application of the SG2524 as a
voltage-regulator control circuit. They can be segregated into three basic categories:
• Capacitor-diode-coupled voltage multipliers
• Inductor-capacitor-implemented single-ended circuits
• Transformer-coupled circuits
Examples of these categories are shown in Figure 7,Figure 8, and Figure 9, respectively. Typical Application
demonstrates how to set up the SG2524 for a capacitor-diode output design. The same techniques for setting up
the internal circuitry of the IC may also be used for the other two output stage examples shown Examples of
Other Output Stages.

10.2.1.2.1 Oscillator
The oscillator controls the frequency of the SG2524 and is programmed by RT and CT as shown in Figure 12.
where
• RTis in kΩ
• CTis in μF
• f is in kHz (1)
Practical values of CT fall between 0.001 μF and 0.1 μF. Practical values of RT fall between 1.8 kΩand 100 kΩ.
This results in a frequency range typically from 130 Hz to 722 kHz.
10.2.1.2.2 Voltage Reference
The 5-V internal reference can be employed by use of an external resistor divider network to establish a
reference common-mode voltage range (1.8 V to 3.4 V) within the error amplifiers (see Figure 11), or an external
reference can be applied directly to the error amplifier. For operation from a fixed 5-V supply, the internal
reference can be bypassed by applying the input voltage to both the VCC and VREF terminals. In this
configuration, however, the input voltage is limited to a maximum of 6 V.

11 Power Supply Recommendations
SGx524 is designed to operate from an input voltage supply range between 8 V and 40 V. This input supply
should be well regulated. If the input supply is located more than a few inches from the device, additional bulk
capacitance may be required in addition to the ceramic bypass capacitors. A tantalum capacitor with a value of
47 μF is a typical choice, however this may vary depending upon the output power being delivered.
12 Layout
12.1 Layout Guidelines
Always try to use a low EMI inductor with a ferrite type closed core. Some examples would be toroid and
encased E core inductors. Open core can be used if they have low EMI characteristics and are located a bit
more away from the low power traces and components. Make the poles perpendicular to the PCB as well if using
an open core. Stick cores usually emit the most unwanted noise.
12.1.1 Feedback Traces
Try to run the feedback trace as far from the inductor and noisy power traces as possible. You would also like
the feedback trace to be as direct as possible and somewhat thick. These two sometimes involve a trade-off, but
keeping it away from inductor EMI and other noise sources is the more critical of the two. Run the feedback trace
on the side of the PCB opposite of the inductor with a ground plane separating the two.
12.1.2 Input/Output Capacitors
When using a low value ceramic input filter capacitor, it should be located as close to the VIN pin of the IC as
possible. This will eliminate as much trace inductance effects as possible and give the internal IC rail a cleaner
voltage supply. Some designs require the use of a feed-forward capacitor connected from the output to the
feedback pin as well, usually for stability reasons. In this case it should also be positioned as close to the IC as
possible. Using surface mount capacitors also reduces lead length and lessens the chance of noise coupling into
the effective antenna created by through-hole components.
12.1.3 Compensation Components
External compensation components for stability should also be placed close to the IC. Surface mount
components are recommended here as well for the same reasons discussed for the filter capacitors. These
should not be located very close to the inductor either.
12.1.4 Traces and Ground Planes
Make all of the power (high-current) traces as short, direct, and thick as possible. It is good practice on a
standard PCB board to make the traces an absolute minimum of 15 mils (0.381 mm) per ampere. The inductor,
output capacitors, and output diode should be as close to each other possible. This helps reduce the EMI
radiated by the power traces due to the high switching currents through them. This will also reduce lead
inductance and resistance as well, which in turn reduces noise spikes, ringing, and resistive losses that produce
voltage errors.
The grounds of the IC, input capacitors, output capacitors, and output diode (if applicable) should be connected
close together directly to a ground plane. It would also be a good idea to have a ground plane on both sides of
the PCB. This will reduce noise as well by reducing ground loop errors as well as by absorbing more of the EMI
radiated by the inductor. For multi-layer boards with more than two layers, a ground plane can be used to
separate the power plane (where the power traces and components are) and the signal plane (where the
feedback and compensation and components are) for improved performance. On multi-layer boards the use of
vias will be required to connect traces and different planes. It is good practice to use one standard via per 200
mA of current if the trace will need to conduct a significant amount of current from one plane to the other.
Arrange the components so that the switching current loops curl in the same direction. Due to the way switching
regulators operate, there are two power states. One state when the switch is on and one when the switch is off.
During each state there will be a current loop made by the power components that are currently conducting.
Place the power components so that during each of the two states the current loop is conducting in the same
direction. This prevents magnetic field reversal caused by the traces between the two half-cycles and reduces
radiated EMI.

IMPORTANT NOTICE
Texas Instruments Incorporated (TI) reserves the right to make corrections, enhancements, improvements and other changes to its
semiconductor products and services per JESD46, latest issue, and to discontinue any product or service per JESD48, latest issue. Buyers
should obtain the latest relevant information before placing orders and should verify that such information is current and complete.
TI’s published terms of sale for semiconductor products (http://www.ti.com/sc/docs/stdterms.htm) apply to the sale of packaged integrated
circuit products that TI has qualified and released to market. Additional terms may apply to the use or sale of other types of TI products and
services.
Reproduction of significant portions of TI information in TI data sheets is permissible only if reproduction is without alteration and is
accompanied by all associated warranties, conditions, limitations, and notices. TI is not responsible or liable for such reproduced
documentation. Information of third parties may be subject to additional restrictions. Resale of TI products or services with statements
different from or beyond the parameters stated by TI for that product or service voids all express and any implied warranties for the
associated TI product or service and is an unfair and deceptive business practice. TI is not responsible or liable for any such statements.
Buyers and others who are developing systems that incorporate TI products (collectively, “Designers”) understand and agree that Designers
remain responsible for using their independent analysis, evaluation and judgment in designing their applications and that Designers have
full and exclusive responsibility to assure the safety of Designers' applications and compliance of their applications (and of all TI products
used in or for Designers’ applications) with all applicable regulations, laws and other applicable requirements. Designer represents that, with
respect to their applications, Designer has all the necessary expertise to create and implement safeguards that (1) anticipate dangerous
consequences of failures, (2) monitor failures and their consequences, and (3) lessen the likelihood of failures that might cause harm and
take appropriate actions. Designer agrees that prior to using or distributing any applications that include TI products, Designer will
thoroughly test such applications and the functionality of such TI products as used in such applications.
TI’s provision of technical, application or other design advice, quality characterization, reliability data or other services or information,
including, but not limited to, reference designs and materials relating to evaluation modules, (collectively, “TI Resources”) are intended to
assist designers who are developing applications that incorporate TI products; by downloading, accessing or using TI Resources in any
way, Designer (individually or, if Designer is acting on behalf of a company, Designer’s company) agrees to use any particular TI Resource
solely for this purpose and subject to the terms of this Notice.
TI’s provision of TI Resources does not expand or otherwise alter TI’s applicable published warranties or warranty disclaimers for TI
products, and no additional obligations or liabilities arise from TI providing such TI Resources. TI reserves the right to make corrections,
enhancements, improvements and other changes to its TI Resources. TI has not conducted any testing other than that specifically
described in the published documentation for a particular TI Resource.
Designer is authorized to use, copy and modify any individual TI Resource only in connection with the development of applications that
include the TI product(s) identified in such TI Resource. NO OTHER LICENSE, EXPRESS OR IMPLIED, BY ESTOPPEL OR OTHERWISE
TO ANY OTHER TI INTELLECTUAL PROPERTY RIGHT, AND NO LICENSE TO ANY TECHNOLOGY OR INTELLECTUAL PROPERTY
RIGHT OF TI OR ANY THIRD PARTY IS GRANTED HEREIN, including but not limited to any patent right, copyright, mask work right, or
other intellectual property right relating to any combination, machine, or process in which TI products or services are used. Information
regarding or referencing third-party products or services does not constitute a license to use such products or services, or a warranty or
endorsement thereof. Use of TI Resources may require a license from a third party under the patents or other intellectual property of the
third party, or a license from TI under the patents or other intellectual property of TI.
TI RESOURCES ARE PROVIDED “AS IS” AND WITH ALL FAULTS. TI DISCLAIMS ALL OTHER WARRANTIES OR
REPRESENTATIONS, EXPRESS OR IMPLIED, REGARDING RESOURCES OR USE THEREOF, INCLUDING BUT NOT LIMITED TO
ACCURACY OR COMPLETENESS, TITLE, ANY EPIDEMIC FAILURE WARRANTY AND ANY IMPLIED WARRANTIES OF
MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT OF ANY THIRD PARTY INTELLECTUAL
PROPERTY RIGHTS. TI SHALL NOT BE LIABLE FOR AND SHALL NOT DEFEND OR INDEMNIFY DESIGNER AGAINST ANY CLAIM,
INCLUDING BUT NOT LIMITED TO ANY INFRINGEMENT CLAIM THAT RELATES TO OR IS BASED ON ANY COMBINATION OF
PRODUCTS EVEN IF DESCRIBED IN TI RESOURCES OR OTHERWISE. IN NO EVENT SHALL TI BE LIABLE FOR ANY ACTUAL,
DIRECT, SPECIAL, COLLATERAL, INDIRECT, PUNITIVE, INCIDENTAL, CONSEQUENTIAL OR EXEMPLARY DAMAGES IN
CONNECTION WITH OR ARISING OUT OF TI RESOURCES OR USE THEREOF, AND REGARDLESS OF WHETHER TI HAS BEEN
ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
Unless TI has explicitly designated an individual product as meeting the requirements of a particular industry standard (e.g., ISO/TS 16949
and ISO 26262), TI is not responsible for any failure to meet such industry standard requirements.
Where TI specifically promotes products as facilitating functional safety or as compliant with industry functional safety standards, such
products are intended to help enable customers to design and create their own applications that meet applicable functional safety standards
and requirements. Using products in an application does not by itself establish any safety features in the application. Designers must
ensure compliance with safety-related requirements and standards applicable to their applications. Designer may not use any TI products in
life-critical medical equipment unless authorized officers of the parties have executed a special contract specifically governing such use.
Life-critical medical equipment is medical equipment where failure of such equipment would cause serious bodily injury or death (e.g., life
support, pacemakers, defibrillators, heart pumps, neurostimulators, and implantables). Such equipment includes, without limitation, all
medical devices identified by the U.S. Food and Drug Administration as Class III devices and equivalent classifications outside the U.S.
TI may expressly designate certain products as completing a particular qualification (e.g., Q100, Military Grade, or Enhanced Product).
Designers agree that it has the necessary expertise to select the product with the appropriate qualification designation for their applications
and that proper product selection is at Designers’ own risk. Designers are solely responsible for compliance with all legal and regulatory
requirements in connection with such selection.
Designer will fully indemnify TI and its representatives against any damages, costs, losses, and/or liabilities arising out of Designer’s non-
compliance with the terms and provisions of this Notice.
