These single output DC-DC converters operate over an input voltage range of 18 to 60 Vdc. The series is also designed to provide a wide output voltage set/trim range of 3.0 to 5.5Vdc, with output current up to 20A at 3.3Vdc or 15A at 5.0Vdc 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. * UL is a registered trademark of Underwriters Laboratories, Inc. † ‡ CSA is a registered trademark of Canadian Standards Association.

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.

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.
