POWER INTEGRATIONS LYT1604D-TL Datasheet & Stock

LYTSwitch™-1 family is ideal for single-stage, high PF, constant current LED bulbs and tubes. This single-stage LED driver IC with combined PFC and constant current output for buck topology family incorporates a high-voltage MOSFET with a variable on-time CrM controller. Extensive protection features with minimum external components provide industry leading power density and functionality. The devices can be used in high-side or low-side non-isolated buck topology. The CrM operation results in low turn-on losses and reduces cost of output diode (slower reverse recovery). LYTSwitch-1 devices are suitable for applications from 2W to 22W.
