UCC28063 PFC Controller

Texas Instruments' natural interleaving transition-mode PFC controller with improved audible noise immunity

Optimized for consumer applications concerned with audible noise elimination, Texas Instruments' solution extends the advantages of transition mode – high efficiency with low-cost components – to higher power ratings than previously possible. By utilizing a Natural Interleaving™ technique, both channels operate as masters (that is, there is no slave channel) synchronized to the same frequency. This approach delivers inherently strong matching, faster responses, and ensures that each channel operates in transition mode. UCC28063 Datasheet

Features	Applications
Input filter and output capacitor ripple-current cancellation Reduced current ripple for higher system reliability and smaller bulk capacitor Reduced EMI filter size Phase management capability FailSafe OVP with dual paths prevents output over-voltage conditions by voltage-sensing failures Sensorless current-shaping simplifies board layout and improves efficiency	Advanced audible noise performance Non-linear error-amplifier gain Soft recovery on overvoltage Integrated brownout and dropout handling Reduced bias currents Improved efficiency and design flexibility over traditional single-phase Continuous Conduction Mode (CCM) Enables use of low-cost diodes without extensive snubber circuitry
