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 technol-
ogy 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.

Absolute Maximum Ratings
Stresses in excess of the absolute maximum ratings can cause permanent damage to th e device. These are absolute stress
ratings only, functional operati on of the device is not implied at these or any other condition s 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 reliabiltiy.
Electrical Specifications
Unless otherwise indicated, specifications apply over all operating input voltage, resistive load, and temperature conditions.
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 application s , 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 in rush
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.

Design Considerations
Input Source Impedance
The power module should be connected to a low
ac-impedance input source. Highly inductive source imped-
ances 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 imped-
ances, consult the factory for further application guideli nes.
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 tran-
sient.
Output capacitance and load impedance interact with the
power module’s output volt age 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 associ-
ated E.S.R. may be dictated, depending on the module’s con-
trol system.
The process of determining the acceptable values
of capacitance and E.S.R. is complex and is
load-dependant. T yco 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 com-
pliance 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 stan-
dards.
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 offic e 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.

voltage is less than 60 Vdc, if the input meets all of the
requirements for SELV, then:
Q
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.
Q
One pole of the input and one pole of the output are to be
grounded, or both circuits are to be kept floating, to main-
tain the output voltage to ground voltage within ELV or
SELV limits.
For all in put 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 evaluate d for SELV:
Q
The input source is to be provided with reinforced insula-
tion from any hazardous voltage, including th e AC mains.
Q
One VI pin and one VO pin are to be reliably earthed, or
both the input and output pins are to be kept floating.
Q
Another SELV reliability test is conducted on the whole
system, as required by the safety agencies, on the combi-
nation 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.

Feature Descriptions
Overcurrent Protection
To provide protection in a fault output overload cond ition, the
module is equipped with internal current-limiting circuitry and
can endure current limit for few seconds. If overcurrent per-
sists for few seconds, the module will shut down and remain
latch-off.
The overcurrent latch is reset by either cycling the inpu t
power or by toggling the on/off pin for one second. If the out-
put overload condition still exists when the module restarts, it
will shut down again. This operation will continue inde finitely
until the overcurrent condition is corrected.
An auto-restart option is also available.
Remote On/Off
T wo 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 collec-
tor 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 cur-
rent 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
For negative logic, short ON/OFF pin to VI(-).
For positive logic: leave ON/OFF pin open.
Figure 52. Remote On/Off Implement ation.
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 termi-
nals must not exceed the output voltage sense range given in
the Feature Sp ecifications table i.e.:
[Vo(+) – Vo(-)] – [SENSE(+) – SENSE(-)] £ 10% of Vo, rated
The voltage between the Vo(+) and Vo(-) terminals must not
exceed the minimum output overvoltage shutdown value indi-
cated in the Feature Specifications table. This limit incl udes
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 define d as
the voltage at the output terminals multiplied by the output
current. When using remote sense and trim: the output volt-
age of the module can be increased, which at the same out-
put 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.
Figure 53. Effective Circuit Configuration for
Single-Mod ule Remote-Sen se Operation
Output Voltage.
Output Overvo ltage 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.
Overtempera tur e Prot ec ti o n
These modu l e s fe ature an overtemperature protection circu i t
to safeguard against thermal damage. The circuit shuts down
and latches off the module when the maximum device refer-
ence 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.

Feature Descriptions (Continued)
Output Voltage Set-Point Adjustment (Trim)
T rimming allows the user to increase or decrease the output
voltage set point of a module. This is accomplished by con-
necting 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 deter-
mines the required external-resistor value to obtain a per-
centage output voltage change of D%.
For Output Voltage: 1.0V - 12V
With an external resistor connected between the TRIM and
SENSE(+) pins (Radj-up), the output voltage set point
(Vo,adj) increases (see Figure 55).
The following equ ation determines the required external-
resistor value to obtain a percentage output voltage change
of D%
For Output Voltage: 1.5V - 12V
For Output Voltage: 1.2V, 1.0V
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 com-
pensation and output voltage set-point adjustment (trim).
See Figure 53.
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 ma ximum
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 multipl ied by the output
current. When using remote sense and trim, the output volt-
age of the module can be increased, which at the same out-
put 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.

Thermal Considerations
The power modules operate in a variety of thermal environ-
ments; however, sufficient cooling should be provided to help
ensure reliable operation of the unit. Heat-d issipating compo-
nents are mounted on the top side of the module. Heat is
removed by conduction, convection and radiation to the sur-
rounding 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.
Note:Top view, pin locations are for reference onl y.
Figure 56. Temperature Meas urement Location.
The temperature at any one of these locations should not
exceed per 1 to ensure reliable operation of the power mod-
ule. The output power of the module should not exceed the
rated power for the module as listed in th e Ordering Informa-
tion table.
Although the maximum Tref temperature of the power mod-
ules is per 1, you can limit these temp eratures to a lower
value for extremely high reliability.
Table 1. Device Temperature
Heat Transfer Without Heat Sinks
Increasing airflow over the module enhances the heat trans-
fer via convection. Figures 57 through 64 shows the maxi-
mum 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.).
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, sys-
tems 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 component s in the system.
The use of output power derating curve is shown in the fol-
lowing example.
What is the minimum airflow necessary for a QRW035A0F
operating at VI = 48 V, an output current of 23A, and a maxi-
mum ambient temperature of 70 °C.

Through-Hole Lead-Free Soldering Infor-

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 sin gle or dual

ant 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 sh ould 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 pr oducts can be processed
with paste-through-hole Pb or Pb-free reflow process. If addi-
tional information is needed, please consult with your Tyco
Electronics 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 Tyco
Electronics Board Mounted Power Modules: Soldering and
Cleaning Application Note (AP01-056EPS).
