ML4822 - ZVS Average Current PFC Controller

General Description

The ML4822 is a PFC controller designed specifically for high power applications.

The controller contains all of the functions necessary to implement an average current boost PFC converter, along with a Zero Voltage Switch (ZVS) controller to reduce diode recovery and MOSFET turn-on losses.

Key Features

  • include undervoltage lockout, overvoltage protection, peak current limiting, and input voltage brownout protection. The ZVS control section drives an external ZVS MOSFET which, combined with a diode and inductor, soft switches the boost regulator. This technique reduces diode reverse recovery and MOSFET switching losses to reduce EMI and maximize efficiency.

May 1997 ML4822* ZVS Average Current PFC Controller GENERAL DESCRIPTION The ML4822 is a PFC controller designed specifically for high power applications. The controller contains all of the functions necessary to implement an average current boost PFC converter, along with a Zero Voltage Switch (ZVS) controller to reduce diode recovery and MOSFET turn-on losses. The average current boost PFC circuit provides high power factor (>98%) and low Total Harmonic Distortion (THD). Built-in safety features include undervoltage lockout, overvoltage protection, peak current limiting, and input voltage brownout protection. The ZVS control section drives an external ZVS MOSFET which, combined with a diode and inductor, soft switches the boost regulator.
