Description

The QPW-series dc-dc converters are a new generation of DC/DC power modules designed for maximum efficiency
and power density. The QPW series provide up to 60A output current in an industry standard quarter brick. The
converter incorporates synchronous rectification technology and innovative packaging techniques to achieve ultra
high efficiency reaching 93% at 3.3V full load. The ultra high efficiency of this converter leads to lower power
dissipation such that for most applications a heat sink is not required. The QPW series power modules are isolated
dc-dc converters that operate over a wide input voltage range of 36 to 75 Vdc and provide single precisely regulated
output. The output is fully isolated from the input, allowing versatile polarity configurations and grounding
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 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 15A (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.

Test Configurations

Note: Measure input reflected-ripple current with a simulated
source inductance (LTEST) of 12 µH. Capacitor CS offsets
possible battery impedance. Measure current as shown
above.

Figure 31. Input Reflected Ripple Current Test
Setup.

Note: Use a 1.0 µF ceramic capacitor and a 10 µF aluminum
or tantalum capacitor. Scope measurement should be made
using a BNC socket. Position the load between 51 mm and
76 mm (2 in. and 3 in.) from the module.

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 31, a
100μF 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.

Output Capacitance

High output current transient rate of change (high
di/dt) loads may require high values of output
capacitance to supply the instantaneous energy
requirement to the load. To minimize the output
voltage transient drop during this transient, low E.S.R.
(equivalent series resistance) capacitors may be
required, since a high E.S.R. will produce a
correspondingly higher voltage drop during the
current transient.

Output capacitance and load impedance interact with
the power module’s output voltage regulation control
system and may produce an ’unstable’ output
condition for the required values of capacitance and
E.S.R.. Minimum and maximum values of output
capacitance and of the capacitor’s associated E.S.R.
may be dictated, depending on the module’s control
system.

The process of determining the acceptable values of
capacitance and E.S.R. is complex and is load­dependant. Lineage Power provides Web-based tools
to assist the power module end-user in appraising
and adjusting the effect of various load conditions and
output capacitances on specific power modules for
various load conditions.

Safety Considerations

For safety agency approval the power module must
be installed in compliance with the spacing and

Feature Descriptions

Overcurrent Protection

To provide protection in a fault output overload
condition, the module is equipped with internal
current-limiting circuitry and can endure current limit
for few seconds. If overcurrent persists for few
seconds, the module will shut down and remain latch­off. The overcurrent latch is reset by either cycling the
input power or by toggling the on/off pin for one
second. If the output overload condition still exists
when the module restarts, it will shut down again. This
operation will continue indefinitely until the
overcurrent condition is corrected.

An auto-restart option is also available.

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 ON/OFF pin, and off during a logic low.
Negative logic remote on/off turns the module off
during a logic high and on during a logic low. Negative
logic, device code suffix "1," is the factory-preferred
configuration. To turn the power module on and off,
the user must supply a switch to control the voltage
between the on/off terminal and the VI (-) terminal
(Von/off). The switch can be an open collector or
equivalent (see Figure 34). A logic low is Von/off = 0
V to I.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 = 15V is 50 µA. If not using the remote on/off
feature, perform one of the following to turn the unit
on:

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

For positive logic: leave ON/OFF pin open.

Figure 34. Remote On/Off Implementation.

Remote Sense

Remote sense minimizes the effects of distribution
losses by regulating the voltage at the remote-sense
connections. The voltage between the remote-sense
pins and the output terminals must not exceed the

Specifications table i.e.:

o,nom

The voltage between the Vo(+) and Vo(-) terminals
must not exceed the minimum output overvoltage
shut-down value indicated in the Feature
Specifications table. This limit includes any increase
in voltage due to remote-sense compensation and
output voltage set-point adjustment (trim). See Figure

35. If not using the remote-sense feature to regulate
the output at the point of load, then connect
SENSE(+) to Vo(+) and SENSE(-) to Vo(-) at the
module.

Although the output voltage can be increased by both
the remote sense and by the trim, the maximum
increase for the output voltage is not the sum of both.
The maximum increase is the larger of either the
remote sense or the trim. The amount of power
delivered by the module is defined as the voltage at
the output terminals multiplied by the output current.
When using remote sense and 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 taken to ensure that
the maximum output power of the module remains at
or below the maximum rated power.

Single-Module Remote-Sense Operation Output

Output Voltage Set-Point Adjustment (Trim)

Trimming 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 SENSE(+) or
SENSE(-) 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 between the TRIM and
SENSE(-) pins (Radj-down), the output voltage set
point (Vo,adj) decreases (see Figure 36). The
following equation determines the required external
resistor value to obtain a percentage output voltage
change of %.

Output Over Voltage Protection

The output overvoltage protection consists of circuitry
that monitors the voltage on the output terminals. If
the voltage on the output terminals exceeds the over
voltage protection threshold, then the module will
shutdown and latch off. The overvoltage latch is reset
by either cycling the input power for one second or by
toggling the on/off signal for one second. The
protection mechanism is such that the unit can
continue in this condition until the fault is cleared.

Over Temperature Protection

These modules feature an overtemperature protection
circuit to safeguard against thermal damage. The
circuit shuts down and latches off the module when
the maximum device reference temperature is
exceeded. The module can be restarted by cycling
the dc input power for at least one second or by
toggling the remote on/off signal for at least one
second.

Input Under/Over Voltage 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 without
Baseplate

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.

Heat-dissipating components are mounted on the top
side of the module. Heat is removed by conduction,
convection and radiation to the surrounding
environment. Proper cooling can be verified by
measuring the thermal reference

The output power of the module should not exceed
the rated power for the module as listed in the
Ordering Information table.

Although the maximum Tref temperature of the power
modules is 110 °C - 115 °C, you can limit this
temperature to a lower value for extremely high
reliability.

Heat Transfer via Convection

Increased airflow over the module enhances the heat
transfer via convection. Following derating figures
shows the maximum output current that can be
delivered by each module in the respective orientation
without exceeding the maximum T
versus local ambient temperature (T
convection through 2m/s (400 ft./min).

Note that the natural convection condition was
measured at 0.05 m/s to 0.1 m/s (10ft./min. to 20
ft./min.); however, systems in which these power
modules may be used typically generate natural
convection airflow rates of 0.3 m/s (60 ft./min.) due to
other heat dissipating components in the system. The
use of Figures 41 - 50 are shown in the following
example:

Thermal Considerations with

The baseplate option (-H) power modules are
constructed with baseplate on topside of the open
frame power module. The baseplate includes quarter
brick through-threaded, M3 x 0.5 mounting hole
pattern, which enable heat sinks or cold plates to
attaché to the module. The mounting torque must not
exceed 0.56 N-m (5 in.-lb.) during heat sink assembly.
This module operates 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

Heat-dissipating components are mounted on the

QPW050/060 Series Power Modules; DC-DC converters

Layout Considerations

The QPW 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.

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
Mounted Power Modules: Soldering and Cleaning

Application Note.

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.
