Description
- DESCRIPTION
- 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 becomes easier and less expensive. A significantly improved multiplier design provides a shared current reference to two independent current amplifiers that ensures matched average current mode control in both PWM outputs while maintaining a stable, low-distortion sinusoidal input line current.
- FEATURES
- • 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 (10 kHz to 300 kHz)
- • Programmable Maximum Duty-Cycle Clamp
- • Programmable Frequency Dithering Rate and Magnitude for Enhanced EMI Reduction
- – Magnitude: 3 kHz to 30 kHz
- – Rate: Up to 30 kHz
- • External Clock Synchronization Capability
- • Enhanced Load and Line Transient Response through Voltage Amplifier Output Slew-Rate
- Correction
- • Programmable Peak Current Limiting
- • Bias-Supply UVLO, Over-Voltage Protection, Open-Loop Detection, and PFC-Enable Monitoring
- • External PFC-Disable Interface
- • Open-Circuit Protection on VSENSE and VINAC pins
- • Programmable Soft Start
- • 20-Lead TSSOP Package
