onsemi NCP1343BADBDEAD1R2G, 1, Voltage Regulator, 25 kHz 9-Pin, SOIC

The ON Semiconductor NCP1343 is a highly integrated quasi−resonant flyback controller suitable for designing high−performance off−line power converters. It integrates power excursion mode (PEM) to minimize transformer size in designs requiring high transient load capability.

Frequency jittering for reduced EMI signature
Latching or auto−recovery timer−based overload protection
Adjustable overpower protection (OPP)
Adjustable maximum frequency clamp
