Description
The SHHD001A3B Hammerhead series power modules are isolated dc-dc converters that operate over an ultra-wide input voltage
range of 18 Vdc -75Vdc (85Vdc, SHHS) and provide a single precisely regulated output voltage at 12Vdc. This series is a low cost,
smaller size alternative to the existing LW/LAW/LC/SC/SW with enhanced performance parameters. The output is fully isolated from
the input, allowing versatile polarity configurations and grounding connections. The modules exhibit high efficiency of 87.5% 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 3A
(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 3A
time-delay 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 1mA, 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 2.4V, and the maximum allowable leakage current at Von/off =
2.4V 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. The unit
operates normally once the output current is brought back into
its specified range. The average output current during hiccup
is 10% IO, max.
Overtemperature Protection
To provide protection under certain fault conditions, the unit is
equipped with a thermal shutdown circuit. The unit will
shutdown if the thermal reference point Tref (Figure 17,
exceeds 125oC (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.
The module shall contain hiccup restart capability.
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 between the TRIM pin and
Vout+ pin (Radj-down), the output voltage set point decreases
(see figure 11). The following equation determines the external
resistor value to obtain an output voltage change from Vo,nom

Feature Descriptions (continued)
The combination of the output voltage adjustment and the
output voltage initial tolerance must not exceed the allowable
trim range of 90% to 110% of the nominal output voltage as
measured between the Vout+ and Vout- pins.
The SHHD power modules have a fixed current-limit set point.
Therefore, as the output voltage is adjusted down, the
available output power is reduced.

Load Share –P Versions
Modules with “P” in the product code are configured with
active droop load sharing capability. Best load current sharing
balance is achieved when the output traces from each module
have the same external Vout+ and Vout- resistance (length x
width) to the location where the traces merge. The module
incorporates diode rectification which insures no reverse
current during parallel startup if one module is ahead of others
during turn-on. Up to 4 modules may be paralleled for
increased load power. Maintain same temperature for all
modules to insure best load share balance.
Figure 13 Output Current Active Droop, -P Option.
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.

Layout Considerations
The SHHD 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 SHHD 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
RoHS-compliant finish that is compatible with both Pb and Pb-
free wave soldering processes. A maximum preheat rate of
3C/s is suggested. The wave preheat process should be such
that the temperature of the power module board is kept below
210C. For Pb solder, the recommended pot temperature is
260C, while the Pb-free solder pot is 270C max. The Through
Hole module is also compatible with paste-in-hole reflow
soldering. Refer to the Reflow Soldering Information section for
process details. If additional information is needed, please
consult with your GE representative for more details.
Surface Mount Information
Pick and Place
The SHHD-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
SHHD-SR series modules are designed to use the main
magnetic component surface to allow for pick and place.

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 21 and 22. For reliable soldering the solder
reflow profile should be established by accurately
measuring the modules CP connector temperatures.

Lead Free Soldering
The –Z version SMT modules of the SHHD 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.
Figure 23 Recommended linear reflow profile using
Sn/Ag/Cu solder.
MSL Rating
The SHHD001A3B series SMT modules have a MSL rating as
indicated int eh Device Code table on the last page.
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 23.
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’s Power Board
Mounted Power Modules: Soldering and Cleaning Application
Note (AN04-001).
