UCC28070-Q1 Overview
The UCC28070 is an advanced power factor correction device that integrates two pulse-width modulators (PWMs) operating 180° out of phase. This interleaved PWM operation generates substantial reduction in the input and output ripple currents, and the conducted-EMI filtering bees easier and less expensive. A significantly improved multiplier design provides a shared current reference to two independent current...
