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 e fficiency reaching 91% at 3.3V
full load. Thanks to the ultra high efficiency of this converter, the power dissipation is such t hat for most applications
a heat sink is not required. In addition, the QRW-series supports future migration of semiconductor and
microprocessor supply voltages do wn to 1.0V .

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 reliabiltiy.

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.
