ML4821 Power Factor Controller

ML4821 Description

May 1997 Micro Linear GENERAL .
The ML4821 provides complete control for a “boost” type power factor correction system using the average current sensing method.

ML4821 Features

* s s s s s s s s s 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 removal Wide common mode range in
