ML4821 controller equivalent, power factor controller.
* Average current sensing for lowest possible harmonic distortion
* Average line compensation with brown-out control
* Precision buffered 5V reference
* 1.
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 precisi.
