UCC2817A Datasheet (Texas Instruments) - BiCMOS Power Factor Preregulator

UCC2817A, BiCMOS Power Factor Preregulator

The UCC3817A and the UCC3818A 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.
