Cxle83173s is a high efficiency non isolated step-down LED constant current driver chip with PWM dimming function, which is suitable for the non isolated step-down LED dimming power

The cxle83173s integrates PWM dimming function. LED output current can be adjusted by duty cycle of external PWM dimming signal. The PWM dimming interface of cxle83173s is simple and can be used with infrared, Bluetooth, 2.4G and other dimming control modules to realize the function of intelligent dimming and color temperature. The cxle83173s integrates high-precision current detection and constant current drive circuit, which can achieve high-precision LED constant current output and excellent line voltage regulation. At the same time, cxle83173s has the advantages of excellent load regulation rate and insensitive to the change of inductance when it works in the inductive current critical mode. Cxle83173s is internally integrated with 500V power tube, and adopts the source driven mode. The working current of the chip is very low, without auxiliary winding detection and power supply, without any compensation elements, only a few peripheral elements, it can achieve high-efficiency LED constant current output, greatly saving the cost and volume of the system
