Description
The KW (Sixteenth-brick) series power modules are isolated dc-dc converters that operate over a wide input voltage range
of 36 to 75Vdc and provide a single precisely regulated output. The output is fully isolated from the input, allowing
versatile polarity configurations and grounding connections. The modules exhibit high efficiency, typical efficiency of 91%
for 3.3V/15A. These open frame modules are available either in surface-mount (-SR) or in through-hole (TH) form.

Absolute Maximum Ratings
36 – 75Vdc Input; 1.2 to 5.0Vdc Output; 10 to 25A Output current
Data Sheet
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.

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 sophisticated power architectures. 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 5 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 sheet for further information.
