ML4821 Power Factor Controller

The ML4821 provides complete control for a “boost” type power factor correction system using the average current sensing method. Special care has been taken in the design of the ML4821 to increase system noise immunity. The circuit includes a precision reference, gain modulator, average current erro.

ML4821 Features

* Average current sensing for lowest possible harmonic distortion

* Average line compensation with brown-out control

* Precision buffered 5V reference

* 1A peak current totem-pole output drive

* Overvoltage comparator eliminates output “runaway” due to load re
