Description
The HW/HC series power modules are isolated dc-dc converters that operate over a wide input voltage range of 18
to 36 Vdc (HC) or 36 to 75 Vdc (HW) and provide one precisely regulated output. The output is fully isolated from
the input, allowing versatile polarity configurations and grounding connections. The modules exhibit high efficiency,
e.g. typical efficiency of 87% 3.3V/5A, 86% at 2.5V/6A. Built-in filtering for both input and output minimizes the need
for external filtering. These open frame modules are available either in surface-mount (-S) or in through-hole form.
Standard features include Remote On/Off, output voltage adjust, overvoltage, overcurrent and overtemperature
protection.

Absolute Maximum Ratings
Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are
absolute stress ratings only, functional operation of the device is not implied at these or any other conditions in
excess of those given in the operations sections of the data sheet. Exposure to absolute maximum ratings for
extended periods can adversely affect the device reliability.

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 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 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. A highly inductive source
impedance can affect the stability of the power module.
For the test configuration in Figure 61, a 33µF
electrolytic capacitor (ESR<0.7Ω 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 1950, CSA C22.2 No. 60950-00, and VDE
0805:2001-12 (IEC60950 3rd Ed).
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 (-B option only).
"All flammable materials used in the manufacturing of
these modules are rated 94V-0 and UL60950 A.2 for
reduced thicknesses. The input to these units is to be
provided with a maximum 3A fast-acting fuse in the
unearthed lead."

Feature Descriptions
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.
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.

VIN(+)
VIN(-)
Ion/off
Von/off
VO
COM
Figure 64. 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 ≤ 1.2V. 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 5.8V, and the maximum allowable leakage
current at Von/off = 5.8V is 10µA.
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(-).
Overtemperature Protection
To provide protection in a fault condition, the unit is
equipped with a thermal shutdown circuit. The unit will
shutdown if the overtemperature threshold of 125 oC is
exceeded at the thermal reference point Tref . Once the
unit goes into thermal shutdown it will then wait to cool
before attempting to restart.
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.
Output Overvoltage Protection
The output overvoltage protection consists of circuitry
that internally clamps the output voltage. If a more
accurate output overvoltage protection scheme is
required then this should be implemented externally via
use of the remote on/off pin.

Voltage
Connecting an external resistor (Rtrim-down) between the
TRIM pin and the COM pin decreases the output voltage
set point. To maintain set point accuracy, the trim
resistor tolerance should be ±0.1%.
The relationship between the output voltage and the trim
resistor value for a ∆% reduction in output voltage is:
Nominal 5V, 3.3V, 2.5V, 2.0V, 1.8V, & 1.5V modules:
Nominal 1.2V module:
Nominal 1.0V module:
Connecting an external resistor (Rtrim-up) between the
TRIM pin and the VO(+) pin increases the output voltage
set point. To maintain set point accuracy, the trim
resistor tolerance should be ±0.5%.
The relationship between the output voltage and the trim
resistor value for a ∆% increase in output voltage is:

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.
The thermal reference point, Tref used in the
specifications is shown in Figure 66. For reliable
operation this temperature should not exceed 115 oC.
Figure 66. Tref Temperature Measurement
Location
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.

For further information on designing for EMC
compliance, please refer to the FLTR100V10 data sheet
(FDS01-043EPS).
Layout Considerations
The HW/HC005 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 FLTR100V10
data sheet.

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.

Surface Mount Information (cont)
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.

Reflow Soldering Information
The HW005 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 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.
The surface mountable modules in the HW005 family
use our newest SMT technology called “Column Pin”
(CP) connectors. Fig 71 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.

Lead Free Soldering
The HW005 family of power modules are designed to
be used in a conventional Tin/Lead (Sn/Pd) solder
process where peak reflow temperatures are limited
to less than 235oC. Users who wish to assemble
these modules in a Lead Free solder process which, it
is expected, will require the use of higher peak reflow
temperatures should contact your local Tyco Power
Systems technical representative for more
information.

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).
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 Tyco Electronics Board
Mounted Power Modules: Soldering and Cleaning
