It also minimizes the dc current flowing through the feedback. Uc3854bn datasheet external divider network connected to VRMS should produce 1. The controller achieves near unity power factor by shaping the ac input line current waveform to correspond to the ac input line voltage. Average current mode control maintains stable, low distortion sinusoidal line current without the need for slope compensation, unlike peak current mode control.

The first is with uc3854bn datasheet internal connection.
