Single-Chip Interleaved PFC Controllers

TI’s new UCC28070 and UCC28060 are the industry’s first single-chip, interleaved power factor correction control circuits. These ICs simplify power design, increase system reliability and achieve greater power factor and high efficiency ratings in applications ranging from multi-kilowatt communication, server and industrial systems, to digital TVs and PCs. That’s High-Performance Analog>>Your Way™

 KEY FEATURES
 UCC28070    UCC28060
Interleaved average current mode PWM control
Advanced current synthesizer for superior efficiency, accurate current sensing and high power factor
Highly linear multiplier output with internal voltage feed-forward correction for near unity power factor
Programmable switching frequency (30 kHz to 300 kHz)
Selectable frequency dithering for reduced EMI
Phase management for high-efficiency light-load operation
 
Improved efficiency and design flexibility over traditional, single-phase continuous conduction mode (CCM)
Input filter and output capacitor current cancellation:
 
- Reduced current ripple for higher system reliability and smaller bulk capacitor
- Reduced EMI filter size
Enables use of low-cost diodes without extensive snubber circuitry
Improved light-load efficiency
Improved transient response
Complete system-level protection
