GENERAL DESCRIPTION
SP201 is a high performance current mode PWM controller for offline flyback converter applications. The IC has built-in General Primary Side CC control, which simplifies isolated power supply design that requires CC regulation of the output.
In SP201, PWM switching frequency with shuffling is fixed...
