HV9123 Description
The Supertex HV9123 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 240VAC line. It contains all the elements required to build a single-switch converter except for the switch, magnetic assembly, output rectifier(s) and filter(s). A unique input circuit allows the HV9123 to self-start directly from a...
