I am looking for a PFC corrected SMPS which should drive my Audio Amplifier (Amp should be cable of Driving Continuous power of 100 W).To my understanding I felt NCP1651(With Flyback Transformer output 36V/3A) would support my requirement with less cost. Please guide me if i am wrong.Suggest me if they are other best solutions.
