The ON Semiconductor NCP1341 is a highly integrated quasi−resonant flyback controller suitable for designing high−performance off−line power converter with an integrated active X2 capacitor discharge feature, the NCP1341 can enable no−load power consumption below 30 mW. It integrates power excursion mode (PEM) to minimize transformer size in designs requiring high transient load capability.

Minimized current consumption for No load power below 30 mW
Frequency jittering for reduced EMI signature
Latching or auto−recovery timer−based overload protection
Adjustable overpower protection (OPP)
