ML4812 Datasheet (Fairchild) - Power Factor Controller

ML4812, Power Factor Controller

The ML4812 is designed to optimally facilitate a peak current control boost type power factor correction system.

Special care has been taken in the design of the ML4812 to increase system noise immunity.

The circuit includes a precision reference, gain modulator, error amplifier, overvoltage protect
