Overview

NCP4326 Secondary Controller for Multi-Output Quasi-Resonant Switchmode Power Supplies This secondary controller significantly improves the overall efficiency and cross−regulation figures when used in a Switchmode Power Supply.

Compared to traditional regulation schemes, the NCP4326 provides superior performance in cross−regulation by individually regulating outputs.

Powered from a main winding, the device actuates two independent switches that precisely adjust the considered outputs to resistor−selectable voltages.
