UCC2817 Datasheet (Texas Instruments) - BiCMOS Power Factor Pregulator

UCC2817, 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.
