Cxle8730 is a continuous current mode buck constant current controller It adopts the unique closed-loop constant current control patent truec2 technology The device is designed to drive multiple

The input voltage range of cxle8730 is up to 10V to 75V DC, and the maximum output current is up to 500mA. The output current of cxle8730 can be programmed externally, and the high-precision output current control scheme only needs ?1% precision detection resistance, less precise filter inductance, and a small number of peripheral devices to achieve very high system constant current precision. The cxle8730 integrates PWM and analog dimming modes. Dimming control signal can directly control LED output current through dim pin.
