The On Semiconductor highly integrated quasi−resonant flyback controller suitable for designing high−performance off−line power converters, this system works down to the 6th valley and transitions to a frequency foldback mode to reduce switching losses, the NCP1340 can enable no−load power consumption below 30 mW, to help ensure converter ruggedness, the NCP1340 implements several key protective features such as internal brownout detection, a non−dissipative Over Power Protection (OPP) for constant maximum output power.
Integrated high−voltage start-up circuit with brownout detection Integrated X2 capacitor discharge capability Wide VCC range from 9 V to 28 V 28 V VCC overvoltage protection Frequency jittering for reduced EMI signature Latching or auto−recovery timer−based overload protection Adjustable overpower protection Fixed or adjustable maximum frequency clamp
