Description

The KHHD010A0A series power modules are isolated DOSA compliant 1/16th brick dc-dc converters that operate over an ultra-

wide input voltage range of 18 Vdc -75Vdc and provide a single precisely regulated output voltage at 5.0Vdc. The output is fully

isolated from the input, allowing versatile polarity configurations and grounding connections. The modules exhibit high efficiency

of 91% typical at full load. Built-in filtering for both input and output minimizes the need for external filtering. The module is fully

self-protected with output over-current and over-voltage, over-temperature and input under voltage shutdown control. Optional

features include negative or positive on/off logic and SMT connections.

CAUTION: This power module is not internally fused. An input line fuse must always be used.

This power module can be used in a wide variety of applications, ranging from simple standalone operation to being part of

complex power architecture. To preserve maximum flexibility, internal fusing is not included; however, to achieve maximum safety

and system protection, always use an input line fuse. The safety agencies require a fast-acting fuse with a maximum rating of 6A

(see Safety Considerations section). Based on the information provided in this data sheet on inrush energy and maximum dc input

current, the same type of fuse with a lower rating can be used. Refer to the fuse manufacturer’s data sheet for further information.

Design Considerations

Input Source Impedance

The power module should be connected to a low

ac-impedance source. Highly inductive source impedance can

affect the stability of the power module. For the test

configuration in Figure 7, a 33μF electrolytic capacitor

(ESR<0.7 at 100kHz), mounted close to the power module

helps ensure the stability of the unit. Consult the factory for

further application guidelines.

Safety Considerations

For safety-agency approval of the system in which the power

module is used, the power module must be installed in

compliance with the spacing and separation requirements of

the end-use safety agency standard, i.e., UL 60950-1-3, CSA

C22.2 No. 60950-00, and VDE 0805 (IEC60950, 3rd Edition).

If the input source is non-SELV (ELV or a hazardous voltage

greater than 60 Vdc and less than or equal to 75Vdc), for the

module’s output to be considered as meeting the requirements

for safety extra-low voltage (SELV), all of the following must be

true:

 The input source is to be provided with reinforced

insulation from any other hazardous voltages, including

the ac mains.

 One VIN pin and one VOUT pin are to be grounded, or both

the input and output pins are to be kept floating.

 The input pins of the module are not operator accessible.

 Another SELV reliability test is conducted on the whole

system (combination of supply source and subject

module), as required by the safety agencies, to verify that

under a single fault, hazardous voltages do not appear at

the module’s output.

Note: Do not ground either of the input pins of the module

without grounding one of the output pins. This may

allow a non-SELV voltage to appear between the output

pins and ground.

The power module has extra-low voltage (ELV) outputs when all

inputs are ELV.

For input voltages exceeding –60 Vdc but less than or equal to

–75 Vdc, these converters have been evaluated to the

applicable requirements of BASIC INSULATION between

secondary DC MAINS DISTRIBUTION input (classified as TNV-2

in Europe) and unearthed SELV outputs.

The input to these units is to be provided with a maximum 6A

fast acting fuse in the ungrounded lead.

Feature Description

Remote On/Off

Two remote on/off options are available. Positive logic turns

the module on during a logic high voltage on the on/off pin,

and off during a logic low. Negative logic remote on/off, device

code suffix “1”, turns the module off during a logic high and on

during a logic low.

Figure 10. Circuit configuration for using Remote On/Off

Implementation.

To turn the power module on and off, the user must supply a

switch (open collector or equivalent) to control the voltage

(Von/off) between the ON/OFF terminal and the VIN(-) terminal.

Logic low is 0V ≤ Von/off ≤ 0.8V. The maximum Ion/off during a

logic low is 0.15mA, the switch should be maintain a logic low

level whilst sinking this current.

During a logic high, the typical Von/off generated by the module

is 4.0V, and the maximum allowable leakage current at Von/off =

4.0V is 25μA.

If not using the remote on/off feature:

For positive logic, leave the ON/OFF pin open.

For negative logic, short the ON/OFF pin to VIN(-).

Overcurrent Protection

To provide protection in a fault (output overload) condition, the

unit is equipped with internal current-limiting circuitry and can

endure current limiting continuously. At the point of

current-limit inception, the unit enters hiccup mode. If the unit

is not configured with auto–restart, then it will latch off

following the over current condition. The module can be

restarted by cycling the dc input power or by toggling the

remote on/off signal. If the unit is configured with the auto-

restart option (4), it will remain in the hiccup mode as long as

the overcurrent condition exists; it operates normally, once the

output current is brought back into its specified range.

Overtemperature Protection

To provide protection under certain fault conditions, the unit is

equipped with a thermal shutdown circuit. The unit will shut

down if the thermal reference point Tref (Figure 16), exceeds

135oC (typical), but the thermal shutdown is not intended as a

guarantee that the unit will survive temperatures beyond its

rating. The module will automatically restart upon cool-down

to a safe temperature.

Input Undervoltage Lockout

At input voltages below the input undervoltage lockout limit,

the module operation is disabled. The module will only begin to

operate once the input voltage is raised above the

undervoltage lockout turn-on threshold, VUV/ON.

Once operating, the module will continue to operate until the

input voltage is taken below the undervoltage turn-off

threshold, VUV/OFF.

Over Voltage Protection

The output overvoltage protection shall consist of circuitry that

independently monitors the output voltage, and shuts the

module down if the output voltage exceeds specified limits.

This protection feature latches in the event of over voltage

across the output. Cycling the on/off pin or input voltage resets

the latching protection feature. If the auto-restart option (4) is

ordered, the module will automatically restart upon an

internally programmed time elapsing.

Output Voltage Programming

Trimming allows the user to increase or decrease the output

voltage set point of the module. This is accomplished by

connecting an external resistor between the TRIM pin and

either the Vout+ pin or the Vout- pin.

Trim Down – Decrease Output Voltage

By connecting an external resistor (Radj-down) between the TRIM

pin and VO(-) or SENSE(-) pin (see figure 11), the output voltage

set point decreases. The following equation determines the

external resistor value to obtain an output voltage change

from Vo,set to the desired Vo,desired:

The combination of the output voltage adjustment and the

output voltage initial tolerance must not exceed the allowable

trim range of 80% to 110% of the nominal output voltage as

measured between the Vout+ and Vout- pins.

The KHHD010A0A power modules have a fixed current-limit set

point. Therefore, as the output voltage is adjusted down, the

available output power is reduced.

Thermal Considerations

The power modules operate in a variety of thermal

environments; however, sufficient cooling should be provided

to help ensure reliable operation.

Considerations include ambient temperature, airflow, module

power dissipation, and the need for increased reliability. A

reduction in the operating temperature of the module will

result in an increase in reliability.

The thermal data presented here is based on physical

measurements taken in a wind tunnel, using automated

thermo-couple instrumentation to monitor key component

temperatures: FETs, diodes, control ICs, magnetic cores,

ceramic capacitors, opto-isolators, and module pwb

conductors, while controlling the ambient airflow rate and

temperature. For a given airflow and ambient temperature, the

module output power is increased, until one (or more) of the

components reaches its maximum derated operating

temperature, as defined in IPC-9592A. This procedure is then

repeated for a different airflow or ambient temperature until a

family of module output derating curves is obtained.

Figure 13. Thermal Test Setup .

Heat Transfer via Convection

Increased airflow over the module enhances the heat transfer

via convection. Derating figures showing the maximum output

current that can be delivered by each module versus local

ambient temperature (TA) for natural convection and up to

3m/s (600 ft./min) are shown in the respective Characteristics

Curves section.

Please refer to the Application Note “Thermal Characterization

Process For Open-Frame Board-Mounted Power Modules” for a

detailed discussion of thermal aspects including maximum

device temperatures.

For further information on designing for EMC compliance,

please refer to the FLTR100V10 data sheet (FDS01-043EPS).

Layout Considerations

The KHHD010A0A power module series are low profile in order

to be used in fine pitch system card architectures. As such,

component clearance between the bottom of the power

module and the mounting board is limited. Avoid placing

copper areas on the outer layer directly underneath the power

module. Also avoid placing via interconnects underneath the

power module.

For additional layout guide-lines, refer to the FLTR100V10 data

sheet.

The KHHD010A0A family of power modules is available for

either Through-Hole (TH) or Surface Mount (SMT) soldering.

Through-Hole Soldering Information

The RoHS-compliant (Z codes) through-hole products use the

SAC (Sn/Ag/Cu) Pb-free solder and RoHS-compliant

components. They are designed to be processed through

single or dual wave soldering machines. The pins have an

Layout Considerations (continued)

RoHS-compliant finish that is compatible with both Pb and Pb-

free wave soldering processes. A maximum preheat rate of

3C/s is suggested. The wave preheat process should be such

that the temperature of the power module board is kept below

210C. For Pb solder, the recommended pot temperature is

260C, while the Pb-free solder pot is 270C max. Not all RoHS-

compliant through-hole products can be processed with paste-

through-hole Pb or Pb-free reflow process. If additional

information is needed, please consult with your GE

representative for more details.

Surface Mount Information

Pick and Place

The KHHD-SR series of DC-to-DC power converters use an

open-frame construction and are designed for surface mount

assembly within a fully automated manufacturing process.

The KHHD-SR series modules are designed to use the main

magnetic component surface to allow for pick and place.

Note: All dimensions in mm [in].

Figure 19. Pick and Place Location.

Z Plane Height

The ‘Z’ plane height of the pick and place location is 7.50mm

nominal with an RSS tolerance of +/-0.25 mm.

Nozzle Recommendations

The module weight has been kept to a minimum by using open

frame construction. Even so, they have a relatively large mass

when compared with conventional SMT components.

Variables such as nozzle size, tip style, vacuum pressure and

placement speed should be considered to optimize this

process.

The minimum recommended nozzle diameter for reliable

operation is 5mm. The maximum nozzle outer diameter, which

will safely fit within the allowable component spacing, is

6.5mm.

Oblong or oval nozzles up to 11 x 6 mm may also be used

within the space available.

For further information please contact your local GE Technical

Sales Representative.

Reflow Soldering Information

These power modules are large mass, low thermal

resistance devices and typically heat up slower than other

SMT components. It is recommended that the customer

review data sheets in order to customize the solder reflow

profile for each application board assembly.

The following instructions must be observed when SMT

soldering these units. Failure to observe these instructions

may result in the failure of or cause damage to the modules,

and can adversely affect long-term reliability.

There are several types of SMT reflow technologies currently

used in the industry. These surface mount power modules

can be reliably soldered using natural forced convection, IR

(radiant infrared), or a combination of convection/IR. The

recommended linear reflow profile using Sn/Pb solder is

shown in Figure 20 and 21. For reliable soldering the solder

reflow profile should be established by accurately measuring

the module’s pin connector temperatures.

Lead Free Soldering

The –Z version SMT modules of the KHHD010A0A series are

lead-free (Pb-free) and RoHS compliant and are compatible in a

Pb-free soldering process. Failure to observe the instructions

below may result in the failure of or cause damage to the

modules and can adversely affect long-term reliability.

Surface Mount Information (continued)

Pb-free Reflow Profile

Power Systems will comply with J-STD-020 Rev. C

(Moisture/Reflow Sensitivity Classification for Nonhermetic

Solid State Surface Mount Devices) for both Pb-free solder

profiles and MSL classification procedures. This standard

provides a recommended forced-air-convection reflow profile

based on the volume and thickness of the package (table 4-2).

The suggested Pb-free solder paste is Sn/Ag/Cu (SAC). The

recommended linear reflow profile using Sn/Ag/Cu solder is

shown in Figure 22.

Figure 22. Recommended linear reflow profile using

Sn/Ag/Cu solder.

MSL Rating

The KHHD010A0A series SMT modules have a MSL rating of 2a.

Storage and Handling

The recommended storage environment and handling

procedures for moisture-sensitive surface mount packages is

detailed in J-STD-033 Rev. A (Handling, Packing, Shipping and

Use of Moisture/Reflow Sensitive Surface Mount Devices).

Moisture barrier bags (MBB) with desiccant are required for

MSL ratings of 2 or greater. These sealed packages should not

be broken until time of use. Once the original package is

broken, the floor life of the product at conditions of  30°C and

60% relative humidity varies according to the MSL rating (see

J-STD-033A). The shelf life for dry packed SMT packages will be

a minimum of 12 months from the bag seal date, when stored

at the following conditions: < 40° C, < 90% relative humidity.

Post Solder Cleaning and Drying Considerations

Post solder cleaning is usually the final circuit board assembly

process prior to electrical board testing. The result of

inadequate cleaning and drying can affect both the reliability

of a power module and the testability of the finished circuit

board assembly. For guidance on appropriate soldering,

cleaning and drying procedures, refer to Lineage Power Board
