POWER INTEGRATIONS LYT0005D Datasheet & Stock

LYTSwitch™-0 family is specifically designed for low cost LED bulb replacement applications. LYTSwitch-0 devices 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 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. Less than




Output current (PF high) of 100mA (MDCM), 140mA (CCM) at 230VAC/60mA (MDCM), 90mA (CCM) at 85-308VAC

Lowest component count, off-line switcher IC for non-isolated LED lighting applications

High power factor meeting EU and USA requirements

Very low component count, frequency jitter reduces EMI, no bias supply or transformer required

Cost-effective LED driver, tight CC performance

Comprehensive protection, LYTSwitch-0 supports different LED applications

Allows designs that easily meet EU and NA standards for PFC in consumer lighting applications

Flyback, buck, buck-boost and boost architectures are all supported by the LYTSwitch-0 family

Accurate current limit with tight line and load regulation that is stable over wide temperature

66KHz operation together with frequency jittering insures a very low cost EMI filter
