ML4822 Datasheet (Micro Linear) - ZVS Average Current PFC Controller

ML4822, ZVS Average Current PFC Controller

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 aver

ML4822 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 MO
