This secondary controller significantly improves the overall efficiency and cross-regulation figures when used in a Switch-Mode 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.
In the end three independent output voltages can be controlled by a single device
A skip cycle feature improves the stand by power in light load condition. Finally, dedicated shutdown pins offer an easy mean to disable the secondary outputs in applications where a low standby power performance is key.
