UCC28019A - PFC Controller

General Description

The UCC28019A 8-pin active Power Factor Correction (PFC) controller uses the boost topology operating in Continuous Conduction Mode (CCM).

The controller is suitable for systems in the 100 W to >2 kW range over a wide-range universal ac line input.

Key Features

  • 1 8-Pin Solution Reduces External Components.
  • Wide-Range Universal AC Input Voltage.
  • Fixed 65-kHz Operating Frequency.
  • Maximum Duty Cycle of 98% (typ. ).
  • Output Over/Undervoltage Protection.
  • Input Brown-Out Protection.
  • Cycle-by-Cycle Peak Current Limiting.
  • Open Loop Detection.
  • Low-Power User-Controlled Standby Mode 2.
