Product Details

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.

Fully integrated auto-restart for short circuit and open loop fault protection – saves external component costs
Programmable line under-voltage detect feature prevents power on/off glitches – saves external components
Frequency jittering dramatically reduces EMI (∼10 dB) – minimizes EMI filter component costs
132 kHz operation reduces transformer size – allows use of EF12.6 or EE13 cores for low cost and small size
Built-in circuitry practically eliminates audible noise with ordinary dip-varnished transformer
