SF1530 Description
SF1530 is a high performance, low cost, highly integrated current mode PWM controller for offline flyback converter applications. PWM switching frequency with shuffling is externally programmable, which can reduce conduction EMI emission of a power supply. When the output power demands decrease, the IC automatically decreases switching frequency for high power conversion efficiency.
