The TNY268 integrates a 700 V power MOSFET, oscillator, high voltage switched current source, current limit, and thermal shutdown circuitry onto a monolithic device IC. 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 TNY268 device incorporates auto-restart, line under-voltage 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.
