LYTSwitch-5 Series AC / DC LED Driver ICs:

The LYTSwitch-5 family is ideal for single-stage power factor corrected constant current LED applications - bulbs, tubes and ballasts. Each device incorporates a high-voltage power MOSFET and discontinuous mode, variable frequency, variable on-time controller and also provides fast (cycle-by-cycle) current limit, input and output OVP, plus advanced thermal management circuitry.
