General Description

The UCC28180 is a flexible and easy-to-use, 8-pin, active Power-Factor Correction (PFC) controller that operates under Continuous Conduction Mode (CCM) to achieve high Power Factor, low current distortion and excellent voltage regulation of boost preregulators in AC - DC front-ends.

The controller is suitable for universal AC input systems operating in 100-W to few-kW range with the switching frequency programmable between 18 kHz to 250 kHz, to conveniently support both power MOSFET and IGBT switches.

An integrated 1.5-A and 2-A (SRC-SNK) peak gate drive output, clamped internally at 15.2 V (typical), enables fast turn-on, turn-off, and easy management of the external power switch without the need for buffer circuits.

Key Features

  • 1 8-Pin Solution (No AC Line Sensing Needed).
  • Wide Range Programmable Switching Frequency (18 kHz to 250 kHz for MOSFET and IGBT-based PFC Converters).
  • Trimmed Current Loop Circuits for Low iTHD.
  • Reduced Current Sense Threshold (Minimizes Power Dissipation in Shunt).
  • Average Current-Mode Control.
  • Soft Over Current and Cycle-by-Cycle Peak Current Limit Protection.
  • Output Overvoltage Protection With Hysteresis Recovery.
  • Audibl.
