UCC28063 Transition-Mode PFC Controller

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

Image of Texas Instruments' UCC28063 Transition-Mode PFC ControllerTexas Instruments' UCC28063 is optimized for consumer applications concerned with audible noise elimination, this 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.

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
  • 100 W to 800 W power supplies
  • Gaming
  • D-to-A set-top boxes
  • Adapters
  • LCD, plasma and DLP™ TVs
  • Home audio systems
