Description
The EQD020 series DC-DC converters are a new generation of open-frame DC/DC power modules designed to
support a 3:1 input voltage range, that allows operation in both 24V or 48V nominal input voltage systems, thus
eliminating the need for separate power modules for each input voltage range. These single output DC-DC
converters operate over an input voltage range of 19 to 60 Vdc. The series is also designed to provide a tightly
regulated output voltage trim range of ± 10% V
O,Set
, with output current up to 20A at 3.3Vdc in an industry standard
eighth brick package. The output is 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.

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 being
part of a complex 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 very
fast-acting surface mount fuse with a maximum rating of 6.3 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.
