UCC28070 Product details

Description

The UCC28070 is an advanced power factor correction (PFC) device that integrates two pulsewidth modulators (PWMs) operating 180° out of phase.

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.
Programmable Frequency from 30 kHz to 300 kHz.
Programmable Maximum Duty-Cycle Clamp.
Programmable Frequency-Dithering Rate and Magnitude for Enhanced EMI Reduction.
Magnitude: 3 kH.
