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
