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. 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
