General Description

The Supertex HV9120 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.

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 HV9120 to self-start directly from a high voltage input, and subsequently take the power to operate from one of the outputs of the converter it is co
