LYTSwitch™-7 LED Driver IC

Power Integrations' LYTSwitch-7 phase-cut dimmable single-stage LED driver IC with combined PFC and constant current output for buck topology

Image of Power Integrations' LYTSwitch-7 Power Integrations' LYTSwitch-7 family is ideal for single-stage, high PF, constant current LED dimmable applications. The 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 CrM operation results in low turn-on losses and reduces cost of output diode (slower reverse recovery). LYTSwitch-7 devices are suitable for applications from 4 W to 22 W. LYTSwitch-7 peak current mode operation is suitable for TRIAC applications without the need of an active bleeder.
