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.

RoHS Compliant

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.

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 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.
