DN05058/D, NCP107X, 12 Vout, Off-line Buck Regulator Design Note

DN05058/D, Design Note describes a very simple, low power, constant voltage output buck power converter intended for powering electronics for white goods, electrical meters, and industrial equipment where isolation from the AC mains is not required. The switching element in the converter is NCP107x series of monolithic switchers. In this reference design, the NCP1071 is utilized with a 100 kHz switching frequency and a maximum output current of 250 mA
