SNVS113E –DECEMBER 1999–REVISED APRIL 2013
PRODUCT DESCRIPTION
The LM3411 is a shunt regulator specifically designed to be the reference and control section in an overall
feedback loop of a regulated power supply. The regulated output voltage is sensed between the IN pin and
GROUND pin of the LM3411. If the voltage at the IN pin is less than the LM3411 regulating voltage (VREG), the
OUT pin sources no current. As the voltage at the IN pin approaches the VREG voltage, the OUT pin begins
sourcing current. This current is then used to drive a feedback device, (opto-coupler) or a power device, (linear
regulator, switching regulator, etc.) which servos the output voltage to be the same value as VREG.
In some applications, (even under normal operating conditions) the voltage on the IN pin can be forced above
the VREG voltage. In these instances, the maximum voltage applied to the IN pin should not exceed 20V. In
addition, an external resistor may be required on the OUT pin to limit the maximum current to 20 mA.
Compensation
The inverting input of the error amplifier is brought out to allow overall closed-loop compensation. In many of the
applications circuits shown here, compensation is provided by a single capacitor connected from the
compensation pin to the out pin of the LM3411. The capacitor values shown in the schematics are adequate
under most conditions, but they can be increased or decreased depending on the desired loop response.
Applying a load pulse to the output of a regulator circuit and observing the resultant output voltage response is a
easy method of determining the stability of the control loop. Analyzing more complex feedback loops requires
additional information.
The formula for AC gain at a frequency (f) is as follows;
where
• Rf≈52 kΩfor the 3.3V part
• Rf≈94 kΩfor the 5V part (1)
The resistor (Rf) in the formula is an internal resistor located on the die. Since this resistor value will affect the
phase margin, the worst case maximum and minimum values are important when analyzing closed loop stability.
The minimum and maximum room temperature values of this resistor are specified in the Electrical
Characteristics section of this data sheet, and a curve showing the temperature coefficient is shown in the
Typical Performance Characteristics section. In the applications shown here, the worst case phase margin
occurs with minimum values of Rf.
Test Circuit
The test circuit shown in Figure 21 can be used to measure and verify various LM3411 parameters. Test
conditions are set by forcing the appropriate voltage at the VOUT Set test point and selecting the appropriate RL
or IOUT as specified in the Electrical Characteristics section. Use a DVM at the “measure” test points to read the
data.

Figure 23. Isolated 1.5A Flyback Switching Regulator Using a LM2577
The LM3411 regulator/driver provides the reference and feedback drive functions in a regulated power supply. It
can also be used together with many different types of regulators, (both linear and switching) as well as other
power semiconductor devices to add precision and improve regulation specifications. Output voltage tolerances
better than 0.5% are possible without using trim pots or precision resistors.
One of the main applications of the LM3411 is to drive an opto-isolator to provide feedback signal isolation in a
switching regulator circuit. For low current applications, (up to 250 mA) the circuit shown in Figure 22 provides
good regulation and complete input/output electrical isolation.
For an input voltage of 15V, this circuit can provide an output of either 3.3V or 5V with a load current up to 250
mA with excellent regulation characteristics. With the part values shown, this circuit operates at 80 kHz., and can
be synchronized to a clock or an additional LM3578. (See LM1578 data sheet for additional information.)
An isolated DC/DC flyback converter capable of higher output current is shown in Figure 23. This circuit utilizes
the LM2577 SIMPLE SWITCHER voltage regulator for the Pulse Width Modulation (PWM), power switch and
protection functions, while the LM3411 provides the voltage reference, gain and opto coupler drive functions. In
this circuit, the reference and error amplifier in the LM2577 are not used (note that the feedback pin is grounded).
The gain is provided by the LM3411. Since the voltage reference is located on the secondary side of the
transformer, this circuit provides very good regulation specifications.
The output of a switching regulator typically will contain a small ripple voltage at the switching frequency and may
also contain voltage transients. These transient voltage spikes can be sensed by the LM3411 and could give an
incorrect regulation voltage. An RC filter consisting of a 1Ωresistor and a 100 nF capacitor will filter these
transients and minimize this problem. The 1Ωresistor should be located on the ground side of the LM3411, and
the capacitor should be physically located near the package.

Figure 25. Negative Input, Negative or Positive Output Flyback Regulator
Improved output voltage tolerance and regulation specifications are possible by combining the LM3411A with one
of the SIMPLE SWITCHER buck regulator IC's, such as the LM2574, LM2575, or LM2576. The circuit shown in
Figure 24 can provide a 5V, ±0.5% Output (1% over the operating temperature range) without using any trim-
pots or precision resistors. Typical line regulation numbers are a 1 mV change on the output for a 8V–18V
change on the input, and load regulation of 1 mV with a load change from 100 mA–1A.
A DC-DC flyback converter that accepts a negative input voltage, and delivers either a positive or negative output
is shown in Figure 25. The circuit utilizes a buck regulator (such as the LM2574, LM2575, or LM2576, depending
on how much output current is needed) operating in a flyback configuration. The LM3411 provides the reference
and the required level shifting circuitry needed to make the circuit work correctly.
A unique feature of this circuit is the ability to ground either the high or low side of the output, thus generating
either a negative or a positive output voltage. Although no isolation is provided, with the addition of an opto-
isolator and related components, this circuit could provide input/output isolation.
Combining a LM3411A-5.0 with a 1A low dropout linear regulator results in a 5V ±0.5% (1% over the operating
temperature range) regulator with excellent regulation specifications, with no trimming or 1% resistors needed.
An added benefit of this circuit (and also true of many of the other circuits shown here) is the high-side and low-
side remote output voltage sensing feature. Sensing the output voltage at the load eliminates the voltage drops
associated with wire resistance, thus providing near perfect load regulation.
A 5V, 1A regulator circuit featuring low dropout, very good regulation specifications, self protection features and
allows output voltage sensing is shown in Figure 26. The regulator used is a LM2941 adjustable low dropout
positive regulator, which also features an ON/OFF pin to provide a shutdown feature.

Figure 27. 3.3V 0.5A Low Dropout Regulator
The circuit in Figure 27 shows a 3.3V low dropout regulator using the LM3411-3.3 and several discrete
components. This circuit is capable of excellent performance with both the dropout voltage and the ground pin
current specifications improved over the LM2941/LM3411 circuit.
The standard LM317 three terminal adjustable regulator circuit can greatly benefit by adding a LM3411.
Performance is increased and features are added. The circuit shown in Figure 28 provides much improved line
and load regulation, lower temperature drift, and full remote output voltage sensing on both the high and low
side. In addition, a precise current limit or constant current feature is simple to add.
Current limit protection in most IC regulators is mainly to protect the IC from gross over-current conditions which
could otherwise fuse bonding wires or blow IC metalization, therefore not much precision is needed for the actual
current limit values. Current limit tolerances can sometimes vary from ±10% to as high as +300% over
manufacturing and temperature variations. Often critical circuitry requires a much tighter control over the amount
of current the power supply can deliver. For example, a power supply may be needed that can deliver 100% of
its design current, but can still limit the maximum current to 110% to protect critical circuitry from high current
fault conditions.
The circuit in Figure 28 can provide a current limit accuracy that is better than ±4%, over all possible variations,
in addition to having excellent line, load and temperature specifications.
Figure 28. Precision Positive Voltage Regulator with Accurate Current Limit
Like the positive regulators, the performance of negative adjustable regulators can also be improved by adding
the LM3411. Output voltages of either 3.3V or 5V at currents up to 1.5A (3A when using a LM333) are possible.
Adding two resistors to the circuit in Figure 29 adds the precision current limit feature as shown in Figure 30.
Current limit tolerances of ±4% over manufacturing and temperature variations are possible with this circuit.

The LM3411 initial room temperature tolerance is ±1% and ±0.5% for the “A” grade part. If a tighter tolerance is
needed, a trim scheme is shown in Figure 32 that provides approximately ±1% adjustment range of the
regulation voltage (VREG).

The LM3411 is ensured to drive a 15 mA load, but if more current is needed, a NPN boost transistor can be
added. The circuit shown in Figure 33 is a shunt regulator capable of providing excellent regulation over a very
wide range of current.

Perhaps one of the simplest applications for the LM3411 is the voltage detector circuit shown in Figure 34 . The
OUT pin is low when the input voltage is less than VREG. When the V(IN) pin rises above VREG, the OUT pin is
pulled high by the internal NPN output resistor.

(2) Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS), Pb-Free (RoHS Exempt), or Green (RoHS & no Sb/Br) - please check http://www.ti.com/productcontent for the latest availability
information and additional product content details.
TBD: The Pb-Free/Green conversion plan has not been defined.
Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements for all 6 substances, including the requirement that
lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.
Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and package, or 2) lead-based die adhesive used between
the die and leadframe. The component is otherwise considered Pb-Free (RoHS compatible) as defined above.
Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame retardants (Br or Sb do not exceed 0.1% by weight
in homogeneous material)

TI does not warrant or represent that any license, either express or implied, is granted under any patent right, copyright, mask work right, or
other intellectual property right relating to any combination, machine, or process in which TI components or services are used. Information
published by TI regarding third-party products or services does not constitute a license to use such products or services or a warranty or
endorsement thereof. Use of such information 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.
Reproduction of significant portions of TI information in TI data books or 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 altered
documentation. Information of third parties may be subject to additional restrictions.
Resale of TI components or services with statements different from or beyond the parameters stated by TI for that component or service

concerning its products, and any use of TI components in its applications, notwithstanding any applications-related information or support
that may be provided by TI. Buyer represents and agrees that it has all the necessary expertise to create and implement safeguards which
anticipate dangerous consequences of failures, monitor failures and their consequences, lessen the likelihood of failures that might cause
harm and take appropriate remedial actions. Buyer will fully indemnify TI and its representatives against any damages arising out of the use
of any TI components in safety-critical applications.
In some cases, TI components may be promoted specifically to facilitate safety-related applications. With such components, TI’s goal is to
help enable customers to design and create their own end-product solutions that meet applicable functional safety standards and
requirements. Nonetheless, such components are subject to these terms.
No TI components are authorized for use in FDA Class III (or similar life-critical medical equipment) unless authorized officers of the parties
have executed a special agreement specifically governing such use.
Only those TI components which TI has specifically designated as military grade or “enhanced plastic” are designed and intended for use in
military/aerospace applications or environments. Buyer acknowledges and agrees that any military or aerospace use of TI components
which have not been so designated is solely at the Buyer's risk, and that Buyer is solely responsible for compliance with all legal and
regulatory requirements in connection with such use.
TI has specifically designated certain components as meeting ISO/TS16949 requirements, mainly for automotive use. In any case of use of
non-designated products, TI will not be responsible for any failure to meet ISO/TS16949.
