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.
