High-Voltage Current-Mode PWM Controller

General 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
