KP201 Overview
KP201 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 KP201, PWM switching frequency with shuffling is fixed to 65 kHz and is trimmed to tight range.
