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 ou
