CR623X is a high performance offline PWM power switch for low power AC/DC charger and adaptor applications.

It operates in primary-side sensing and provides constant voltage (CV) and constant current (CC) regulation without TL431 and opto-coupler.

A typical output CC/CV curve is shown as in the Fig.1.
