Controller Featuring Valley Lock-Out Switching, High-Voltage, Quasi-Resonant Flyback Controller for NCP1340 for

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.
