UCC2817-EP Product details

Description

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.Average current mode control maintains stable, low-distortion sinusoidal line current.Designed with TI's BiCMOS process, the UCC2817 and UCC2818 offers new
