UCC28070 Datasheet - Texas Instruments

UCC28070 PFC Controller

The UCC28070 is an advanced power factor correction (PFC) device that integrates two pulsewidth modulators (PWMs) operating 180° out of phase. This interleaved PWM operation generates substantial reduction in the input and output ripple currents, allowing the conducted-EMI filtering to become easier.

UCC28070 Features

* 1 Interleaved Average Current-Mode PWM Control With Inherent Current Matching

* Advanced Current Synthesizer Current Sensing for Superior Efficiency

* Highly-Linear Multiplier Output With Internal Quantized Voltage Feed-Forward Correction for Near-Unity PF
