U620XC Data Sheet Offline Current Mode PWM Power Switch with Built-in CC Regulation  Description U620XC is a high performance current mode PWM power switch 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 U620XC, PWM switching frequency with shuffling is fixed to 65KHz and is trimmed to tight range. The IC has built-in green and burst mode control for light and zero loadings, which can achieve less than 75mW standby power .
