The UCC28070PWG4 incorporates several innovations, including current synthesis and quantized voltage feed-forward, to improve PF, efficiency, THD, and transient response. It is a sophisticated power factor correction (PFC) device that combines two 180° out of phase pulse width modulators (PWMs). Frequency dithering, clock synchronization, and slew rate enhancement are additional features that can improve performance. UCC28070PWG4
