Product Summary

The HV9123NG is a Switch Mode Power Supply (SMPS) controller subsystem that can start and run directly from almost any DC input, from a 12V battery to a rectified and filtered 240V AC line. The HV9123NG contains all the elements required to build a single-switch converter except for the switch, magnetic assembly, output rectifier(s) and filter(s). The applications of the HV9123NG are Off-line high frequency power supplies, Universal input power supplies, High density power supplies, Very high efficiency power supplies, Extra wide load range power supplies.
