The module achieves typical full load efficiency of 92% at 3.3Vdc output voltage. The open frame modules construction, available in through-hole packaging, enables designers to develop cost- and space-efficient solutions. * 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 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 manufacturer’s data sheet for further information. April 23, 2021 ©2014 General Electric Company. All rights reserved.

The extended Tdelay will occur when the module restarts following the rapid cycling of Vin from normal levels to less than the Input Undervoltage Lockout (which causes module shutdown), and then back to normal. The module requires a minimum of 470 μF external output capacitor to prevent shutdown during full load to no load transients and to avoid exceeding the OVP maximum limits during startup into open loop fault conditions.
