具有 10.5V/10V UVLO、温度范围为 -40°C 至 85°C 的 6kHz 至 220kHz CCM PFC 控制器

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.
