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