The dc module achieves typical full load efficiency of 92% at 3.3V output voltage. The open frame modules construction, available in dc through-hole packaging, enables designers to develop cost- and space-efficient solutions. * UL is a registered trademark of Underwriters Laboratories, Inc.

Page 1 Datasheet GE ESTW025A0F Series: Eighth-Brick Power Modules 36 to 75V Input 3.3V , 25A dc dc 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 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 fast-acting 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 manufacturers data sheet for further information. April 23, 2021 2014 General Electric Company. All rights reserved. Page 2
