UCC2818A-Q1 Datasheet (Texas Instruments) - BiCMOS Power-Factor Preregulator

UCC2818A-Q1, BiCMOS Power-Factor Preregulator

The UCC2818A-Q1 device 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 maintains stable
