Cxle8793e is a step-down LED driver chip applied to DC-DC constant output current. It is internally integrated with LED constant current control, PWM dimming, over temperature protection and other functional modules. It is suitable for 5VDC ~ 60VDC input voltage and output current is set through external RCS resistance. At the same time, the dim port can receive PWM signal to adjust the output current, the constant current accuracy is less than ?3%, the peripheral components are few, and the scheme cost is low.
