Power Management Reference Designs

The L4981 integrated circuit is a continous mode average current controller with several specific functions for active power factor correction. It can operate in high quality, medium/high power conversion range and provides all the necessary features to achieve a very high power factor, up to 0.99. Thanks to the BCD technology used, operative switching frequency higher than 200kHz can be used.
