UCC2817-EP Datasheet (Texas Instruments) - BiCMOS POWER-FACTOR PREREGULATOR

UCC2817-EP, BiCMOS POWER-FACTOR PREREGULATOR

ORDERING INFORMATION The UCC2817 and UCC2818 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.
