ONSEMINCP1342ENDCEAD1R2GAC-DC Converter 9-Pin, SOIC NCP1342ENDCEAD1R2G

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. To ensure light load performance with high frequency designs, the NCP1342 incorporates Rapid Frequency Fold back with Minimum Peak Current Modulation to reduce the switching frequency quickly.
