Power Integrations LYT0004P, LED Driver IC, Minimum of 50 V, PDIP-8B

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.
