LYTSwitch-0 Off-Line Low Power LED Driver ICs

Power Integrations LYTSwitch-0 Off-Line Low Power LED Driver ICs integrate a 700V 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 and allows discrete inductors to be used. The fully integrated auto-restart circuit in the Power Integrations LYTSwitch-0 family safely limits output power during fault conditions such as short-circuit or open-loop, reducing component count.
