UCC28063A - PFC CONTROLLER

Description

This part is identical to UCC28063 with the exception that the TSET pin Open/ Short Fault Detect and the CS pin Open Fault Detect

Features

  • 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.
  • Fail-Safe OVP with Dual Paths Prevents Output Overvoltage Conditions by Voltage-Sensing Failures.
  • Sensorless Current-Shaping Simplifies Board Layout and Improves Efficiency.
  • Advanced Audible Noise Performance.
  • Non-linear Error-Am.
