Description The LYTSwitch™-0 family is specifically designed for low cost LED bulb replacement applications. LYTSwitch-0 devices integrate a 700 V power MOSFET， oscillator， simple ON/OFF control scheme， a high-voltage switched current source， frequency jittering， cycle-by-cycle current limit and thermal shutdown circuitry into a monolithic IC. The start-up and operating power are derived directly from the voltage on the DRAIN pin. This eliminates the need for a bias supply and associated circuitry plus allowing low-cost discrete inductors to be used. The fully integrated auto-restart circuit in the LYTSwitch-0 family safely limits output power during fault conditions such as short-circuit or open-loop， reducing component count and lower system cost. Package options for thru-hole and surface-mount suit different manufacturing requirements.
