LYTSwitch-4 Series AC / DC LED Driver ICs:

The LYTSwitch-4 family enables off-line LED drivers with high power factor which easily meet international requirements for THD and harmonics. Efficiency of up to 92% is easily achieved in typical applications. LYTSwitch-4 ICs are highly integrated and employ a primary-side control technique that eliminates the optoisolator and reduces component count.
