Description
The QRW-series dc-dc converters are a new generation of DC/DC power modules designed for optimum
efficiency and power density. The QRW series provide up to 40A output current in an industry standard quarter brick, which makes
it an ideal choice for small space, high current and low voltage applications. The converter uses synchronous rectification technology and innovative packaging techniques to achieve ultra high efficiency reaching 91% at 3.3V full load. Thanks to the ultra high
efficiency of this converter, the power dissipation is such that for most applications a heat sink is not required. In addition, the
QRW-series supports future migration of semiconductor and microprocessor supply voltages down to 1.0V.

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 normal-blow fuse with a
maximum rating of 10 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 for further information.

The power module should be connected to a low
ac-impedance input source. Highly inductive source impedances can affect the stability of the power
module. For the test configuration in 49,
a 33 µF electrolytic capacitor (ESR < 0.7 W at 100 kHz)
mounted close to the power module helps ensure
stability of the unit. For other highly inductive source impedances, 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. Tp 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
load-dependant. Lineage 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 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 and 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:

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 10A normal-blow fuse in the ungrounded lead.

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
latch-off.
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 factorypreferred configuration.
The voltage between the Vo(+) and Vo(-) terminals must not
exceed the minimum output overvoltage shutdown 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 53.
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 tine 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.
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 10). 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, do one of the following
to turn the unit on

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 output voltage sense range given in
Lineage Power
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.
Overtemperature 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.

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 54). The following equation determines the required external-resistor value to obtain a percentage output voltage change of D%.
For Output Voltage: 1.0V - 12V
With an external resistor connected between the TRIM and

Heat Transfer Without Heat Sinks
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-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 temperature of selected components on the
topside of the power module (See 56). Peak temperature
(Tref) can occur at any of these positions indicated in Figure
50.
Increasing airflow over the module enhances the heat transfer via convection. Figures 57 through 64 shows the maximum current that can be delivered by the corresponding
module without exceeding the maximum case temperature
versus local ambient temperature (TA) for natural convection
through 2 m/s (400 ft./min.).

OUTPUT
Thermal Considerations
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 output power derating curve is shown in the following example.
What is the minimum airflow necessary for a QRW035A0F
operating at VI = 48 V, an output current of 23A, and a maximum ambient temperature of 70 °C.
Solution
Given: VI = 48V

TA = 70 °C
Determine airflow (v) (Use Figure 62):

Note:Top view, pin locations are for reference only.

The temperature at any one of these locations should not
exceed per 1 to ensure reliable operation of the power module. 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 per 1, you can limit these temperatures to a lower
value for extremely high reliability.

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 System representative for more details.
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 (AP01-056EPS).

Note: Legacy device codes may contain a -B option suffix
to indicate 100% factory Hi-Pot tested to the isolation voltage specified in the Absolute Maximum Ratings table. The
100% Hi-Pot test is now applied to all device codes, with or
without the -B option suffix. Existing comcodes for devices
with the -B suffix are still valid; however, no new comcodes
for devices containing the -B suffix will be created.
