SF1533 General Description

SF1533 is a high performance, high efficiency, highly integrated current mode PWM power switch for offline flyback converter applications. In SF1533, PWM switching frequency with shuffling is fixed to 50KHz and is trimmed to tight range. When the output power demands decrease, the IC decreases switc.
