Description
The KHHD015A0F series power modules are isolated DOSA compliant 1/16th brick dc-dc converters that operate over an ultrawide input voltage range of 18 V
-75Vdc and provide a single precisely regulated output voltage at 3.3Vdc. The output is fully
dc
isolated from the input, allowing versatile polarity configurations and grounding connections. The modules exhibit high efficiency
of 90.5% 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, 3
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 V
pin and one V
IN
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
) between the ON/OFF terminal and the VIN(-) terminal.
(V

Logic low is 0V ≤ V
≤ 0.8V. The maximum I
on/off
logic low is 0.15mA, the switch should be maintain a logic low
level whilst sinking this current.
During a logic high, the typical V
is 4.0V, and the maximum allowable leakage current at V
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 V
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 autorestart 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
o
C (typical), but the thermal shutdown is not intended as a
135
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, V
UV/ON
.
Once operating, the module will continue to operate until the
input voltage is taken below the undervoltage turn-off
threshold, V
UV/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 V
voltage set point decreases. The following equation
determines the external resistor value to obtain an output

Layout Considerations (continued)
RoHS-compliant finish that is compatible with both Pb and Pbfree 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 270C max. Not all RoHS-
compliant through-hole products can be processed with pastethrough-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 KHHD015A0F 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.

MSL Rating
The KHHD015A0F 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 GE Board Mounted
Power Modules: Soldering and Cleaning Application Note
(AP01-056EPS).
