Description

TinySwitch™-II integrates a 700 V power MOSFET, oscillator,

high voltage switched current source, current limit and thermal

shutdown circuitry onto a monolithic device. The start-up and

operating power are derived directly from the voltage on the

DRAIN pin, eliminating the need for a bias winding and associated

circuitry. In addition, the TinySwitch-II devices incorporate

auto-restart, line undervoltage sense, and frequency jittering. An

innovative design minimizes audio frequency components in the

simple ON/OFF control scheme to practically eliminate audible

noise with standard taped/varnished transformer construction.
