Description
The EQW series, Eighth-brick power modules are isolated dc-dc converters that can deliver up to 25A of output current
and provide a precisely regulated output voltage over a wide range of input voltages (Vi = 36 -75Vdc). The modules
achieve full load efficiency of 88% at 3.3V output voltage. The open frame modules construction, available in both
surface-mount and through-hole packaging, enable designers to develop cost- and space-efficient solutions. Standard
features include remote On/Off, remote sense, output voltage adjustment, overvoltage, overcurrent and overtemperature
protection.

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.

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
fast-acting fuse with a maximum rating of 6A (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.
