Description
The HW series power modules are isolated dc-dc converters that can deliver up to 12A of output current and provide a precisely
regulated output voltage over a wide range of input voltages (VI = 36 V to 75 Vdc for HW modules). The modules achieve full load
efficiency of 90% at 3.3 V output voltage. The open frame modules, available in both surface-mount and through-hole packaging,
enable designers to develop cost- and space-efficient solutions. Standard features include remote On/Off, output voltage adjustment, overvoltage, overcurrent and overtemperature protection.

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 stand-alone operation to an integrated
part of a sophisticated 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 time-delay fuse with a
maximum rating of 5 A (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.

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., UL60950, CSA C22.2
No. 60950-00, and
VDE 0805:2001-12 (IEC60950, 3rd Ed).
These converters have been evaluated to the spacing
requirements for Basic Insulation, per the above safety standards.
For Basic Insulation models ("–B" Suffix), 1500 Vdc is
applied from VI to VO to 100% of outgoing production.
For end products connected to –48 Vdc, or –60 Vdc nomianl
DC MAINS (i.e. central office dc battery plant), no further
fault testing is required.
Note:–60 V dc nominal bettery plants are not available in the
U.S. or Canada.
For all input voltages, other than DC MAINS, where the input
voltage is less than 60 Vdc, if the input meets all of the
requirements for SELV, then:
n
The output may be considered SELV. Output voltages will
remain withing SELV limits even with internally-generated
non-SELV voltages. Single component failure and fault
tests were performed in the power converters.
n
One pole of the input and one pole of the output are to be
grounded, or both circuits are to be kept floating, to maintain the output voltage to ground voltage within ELV or
SELV limits.
For all input sources, other than DC MAINS, where the input
voltage is between 60 and 75 Vdc (Classified as TNV-2 in
Europe), the following must be adhered to, if the converter’s
output is to be evaluated for SELV:
n
The input source is to be provided with reinforced insulation from any hazardous voltage, including the AC mains.
n
One VI pin and one VO pin are to be reliably earthed, or
both the input and output pins are to be kept floating.
n
Another SELV reliability test is conducted on the whole
system, as required by the safety agencies, on the combination of supply source and the subject module to verify
that under a single fault, hazardous voltages do not
appear at the module’s output.
The power module has ELV (extra-low voltage) outputs
when all inputs are ELV.
All flammable materials used in the manufacturing of these
modules are rated 94V-0, and UL60950A.2 for reduced
thicknesses. The input to these units is to be provided with a
maximum 5A time-delay in the unearthed lead.

Design Considerations
Input Source Impedance
The power module should be connected to a low
ac-impedance source. A highly inductive source impedance
can affect the stability of the power module. For the test configuration in Figure 37, a 33µF electrolytic capacitor
(ESR<0.7W at 100kHz), mounted close to the power module
helps ensure the stability of the unit. Consult the factory for
further application guidelines.
Feature Descriptions
Remote On/Off
Two remote On/Off options are available. Positive logic
remote On/Off turns the module on during a logic-high voltage on the remote ON/OFF pin, and off during a logic low.
Negative logic remote On/Off, device code suffix "1", turns
the module off during logic-high voltage and on during a logic
low.
To turn the power module on and off, the user must supply a
switch to control the voltage betw e en the
ON/OFF pin and the VI(–) terminal. The switch may be an
open collector or equivalent (see Figure 40). A logic low is
Von/off = –0.7 V to 1.2 V. The maximum Ion/off during a logic
low is 1 mA. The switch should maintain a logic-low voltage
while sinking 1 mA. During a logic high, the maximum Von/off
generated by the power module is 15 V. The maximum allowable leakage current of the switch at Von/off = 15 V is 50 µA.
If not using the remote on/off feature, do one of the following:
For positive logic, leave the ON/OFF pin open.
For negative logic, short the ON/OFF pin to VI(–).

Output Voltage Set-Point Adjustment (Trim)
Output voltage trim allows the user to increase or decrease
the output voltage set point of a module. This is accomplished by connecting an external resistor between the TRIM
pin and either the VO(+) or VO(–) pins. The trim resistor
should be positioned close to the module. If not using the trim
feature, leave the TRIM pin open.
With an external resistor Trim-down between the TRIM and
VO(–) pins, the output voltage set point VO, set decreases
(see Figure 41). The following equation determines the
required external-resistor value to trim-down the output voltage from VO, set to VO:

The amount of power delivered by the module is defined as
the voltage at the output terminals multiplied by the output
current. When using trim, the output voltage of the module
can be increased, which at the same output current would
increase the power output of the module. Care should be

Overcurrent Protection
To provide protection in an output overload fault condition,
the module is equipped with internal current-limiting circuitry,
and can endure current limiting for an unlimited duration. At
the instance of current-limit inception, the module enters a
"hiccup" mode of operation, whereby it shuts down and automatically attempts to restart. While the fault condition exists,
the module will remain in this mode until the fault is cleared.
The unit operates normally once the output current is
reduced back into its specified range.
Output Overvoltage Protection
The output overvoltage protection clamp consists of control
circuitry, independent of the primary regulation loop, that
monitors the voltage on the output terminals. This control
loop has a higher voltage set point than the primary loop
(See the overvoltage clamp values in the Feature Specifications Table). In a fault condition, the overvoltage clamp
ensures that the output voltage does not exceed VO, ovsd,
max. This provides a redundant voltage-control that reduces
the risk of output overvoltage.

Overtemperature Protection
To provide protection under certain fault conditios, the unit is
equipped with a thermal shutdown circuit. The unit will shudown if the overtemperature threshold is exceeded, but the
thermal shut down is not intended as a guarantee that the
unit will survive temperatures beyond its rating. The module
will automatically restart after it cools down.
Input Undervoltage Lockout
At input voltages below the input undervoltage lockout limit,
the module operation is disabled. The module will begin to
operate at an input voltage above the undervoltage lockout
turn-on threshold.

Thermal Considerations
The power modules operate in a variety of thermal environments; however, sufficient cooling should be provided to help
ensure reliable operation of the unit. Heat is removed by conduction, convection, and radiation to the surrounding environment. Proper cooling can be verified by measuring drain pin
Q203 at the position indicated in Figure 43.
The temperature at Q203 drain pins should not exceed 115
°C. The output power of the module should not exceed the
rated power for the module
(VO, set x IO, max).
Although the maximum operating ambient temperature of the
power modules is 85 °C, you can limit this temperature to a
lower value for extremely high reliability.
rent that can be delivered by various modules versus local
ambient temperature (TA) for natural convection through 2 m/
s (400 ft./min.).
Systems in which these power modules may be used typically generate natural convection airflow rates of 0.3 ms
–1
(60 ft./min.) due to other heat-dissipating components in the
system. Therefore, the natural convection condition represents airflow rates of up to 0.3 ms
–1
(60 ft./min.). Use of Fig-
ure 44 is shown in the following example.
Example
What is the minimum airflow necessary for a HW010A0F1

Through-Hole Lead-Free Soldering Information
The RoHS-compliant 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 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
Lineage Power representative for more details.
Surface Mount Information
Pick and Place Area
Although the module weight is minimized by using openframe construction, the modules have a relatively large mass
compared to conventional surface-mount components. T o
optimize the pick-and-place process, automated vacuum
equipment variables such as
nozzle size, tip style, vacuum pressure, and placement
speed should be considered. Surface-mount versions of this
family have a flat surface which serves as a
pick-and-place location for automated vacuum equipment.
The module’s pick-and-place location is identified in Figure
49.
sure and placement speed should be considered to optimize
this process.
The minimum recommended nozzle diameter for reliable
operation is 6mm. The maximum nozzle outer diameter,
which will safely fit within the allowable component spacing,
is 9 mm.
Oblong or oval nozzles up to 11 x 9 mm may also be used
within the space available.
For further information please contact your local Lineage
Power Technical Sales Representative.
Reflow Soldering Information
The HW006 family of power modules is available for either
Through-Hole (TH) or Surface Mount (SMT) soldering.
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 orde r 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.
The surface mountable modules in the HW006 family use our
newest SMT technology called "Col umn Pin" (CP) connectors. Figure 50 shows the new CP connector before and after
reflow soldering onto the end-board assembly.

Reflow Soldering.
The CP is constructed from a solid copper pin with an integral
solder ball attached, which is composed of tin/lead (Sn/Pb)
solder. The CP connector design is able to compensate for
large amounts of co-planarity and still ensure a reliable SMT
solder joint.
Typically, the eutectic solder melts at 183oC, wets the land,
and subsequently wicks the device connection. Sufficient
time must be allowed to fuse the plating on the connection to
ensure a reliable solder joint. 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. For reliable soldering the
solder reflow profile should be established by accurately
measuring the modules CP connector temperatures.

ages 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

Solder Ball and Cleanliness Requirements
The open frame (no case or potting) power module will meet
the solder ball requirements per J-STD-001B. These requirements state that solder balls must neither be loose nor violate
the power module minimum electrical spacing.
The cleanliness designator of the open frame power module
is C00 (per J specification).
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. 53.
MSL Rating
The HW series SMT modules have a MSL rating of 1.
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 pack-
