ML4821 Power Factor Controller

ML4821 Description

www.fairchildsemi.com ML4821 Power Factor Controller .
The ML4821 provides complete control for a “boost” type power factor correction system using the average current sensing method.

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
