UCC3817 Datasheet - Texas Instruments

UCC3817 BiCMOS Power Factor Pregulator

The UCCx817 and UCCx818 family provides all the functions necessary for active power factor-corrected preregulators. The controller achieves near-unity power factor by shaping the AC input line current waveform to correspond to that of the AC input line voltage. Average current mode control maintain.
