Power Integrations, LED Driver IC, Minimum of 50 V, SOIC LYT0004D

LYTSwitch-0 series LED Driver AC-DC Converters. The Power Integrations LYTSwitch™-0 family of low-power AC-DC converters is specifically designed for low cost LED lamp replacement applications. The devices integrate a high voltage power MOSFET with the required control circuitry to implement a compact and efficient solution suitable for a variety of converter topologies. The LYT0004, LYT005 and LYT006 types include an auto restart function which operates after a fault or overload condition has occurred. Package options include both through-hole and surface-mount devices to suit different manufacturing requirements. High power factor meeting EU and USA requirements Very low component count 66 kHz operation with frequency jitter reduces EMI No bias supply or transformer required Good constant current regulation Accurate current limit with tight line and load regulation Protection for over-temperature, short-circuit, open-circuit and open loop faults Suitable for flyback, buck, buck-boost and boost architectures
