Product Overview

The UCC28061D is a natural interleaving transition-mode Power Factor Correction (PFC) Controller with improved audible noise immunity. 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. Complete system-level protections feature input brownout, output over-voltage, open-loop, overload, soft-start, phase-fail detection and thermal shutdown. The additional FailSafe over-voltage protection (OVP) feature protects against shorts to an intermediate voltage that, if undetected, could lead to catastrophic device failure.
  • Easy phase management facilitates compliance to light-load efficient standards
  • Sensorless current shaping simplifies board layout and improves efficiency
  • Inrush safe current limiting
  • Prevents MOSFET conduction during inrush
  • Eliminates reverse recovery events in output rectifiers
  • Improved audible noise performance
  • Soft start on overvoltage
  • Integrated brownout
  • 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 diodes without extensive snubber circuitry
  • Improved light-load efficiency
  • Improved transient response
  • Complete system-level protection
