LYTSwitch-7 Series AC / DC LED Driver ICs:

The 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.
