NCP4326 Datasheet | onsemi

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. pared 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. This controller also integrates a precision reference voltage, which together with a dedicated operational amplifier reduces the feedback loop elements to the minimum. In the...
