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, which makes it an ideal choice for small space, high current and low voltage
applications. 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

QPW050/060A Series Power Modules; dc-dc Converters
36 – 75 Vdc Input; 1.2Vdc to 3.3Vdc Output
Data Sheet
Sept 16, 2003
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. Built-in filtering for both input and
output minimizes the need for external filtering.
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.

Fusing Considerations
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
time-delay
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.
