SCT2302 2-Channel High Constant Driver

The SCT2302 is a patented logical feedback for automatic supply regulation to minimize the system power consumption. The SCT2302 is a two channels constant current driver for LED lighting. It provides the PWM dimming by sinking constant current from LED clusters with minimum pulse width 20us. The dimming control is performed by connecting the PWM signal from.
