Datasheet - NCP1342BMDCDD1R2G

The ON Semiconductor series NCP1342 is a highly integrated quasi−resonant fly back controller suitable for designing high−performance off−line power converters. With an integrated active X2 capacitor discharge feature, the NCP1342 can enable no−load power consumption below 30 mW.

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

Abnormal Overcurrent Fault Protection for Winding Short Circuit or

Saturation Detection

Internal Temperature Shutdown

Valley Switching Operation with Valley−Lockout for Noise−Free Operation

Frequency Fold back with 25 kHz Minimum Frequency Clamp for Increased Efficiency at Light Loads
