SF1565SG Overview
SF1565 is a high performance, highly integrated current mode PWM controller for medium to large offline flyback converter applications. In SF1565, the PWM switching is internally trimmed to tight range. To improve EMI performance, the IC integrates frequency shuffling function to reduce conduction EMI emission of a power supply.
