These modules provide a precisely regulated output voltage programmable via an external resistor from 0.75Vdc to 4.0Vdc over a wide range of input voltage (VIN = 3.0 5.8Vdc). Their open- frame construction and small footprint enable designers to develop cost- and space-efficient solutions. Standard features include remote On/Off, programmable output voltage, overcurrent and overtemperature protection. * UL is a registered trademark of Underwriters Laboratories, Inc.

GE Data Sheet TM Austin MicroLynx 5A: Non-Isolated DC-DC Power Modules 3.0Vdc 5.8Vdc input 0.75Vdc to 4.0Vdc output 5A Output Current 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.

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 fast-acting fuse with a maximum rating of 6 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 manufacturers data sheet for further information. July 24, 2020 2013 General Electric Company. All rights reserved. Page 2
