Cxle8358 high power factor non isolated step-down LED constant current driver chip with three section switch dimming function chip integrates a single-stage active power factor correction circuit

Cxle8358 integrates three section switch dimming function. The output current of LED can be switched between 100%, 50% and 10% through the switch action of common switch. Cxle8358's dimming mode is simple and convenient. It only needs ordinary switches without additional dimmers, which simplifies the design of LED lighting system.
The cxle8358 integrates a single-stage active power factor correction circuit. The system can achieve high power factor and low total harmonic distortion of input current. Cxle8358 works in quasi resonant switch mode, and the power tube is in zero current state. This effectively reduces the switching loss of the power tube and improves the EMI characteristics of the system.
Cxle8358 adopts the proprietary closed-loop feedback control technology, and the chip can achieve high-precision LED constant current output. The cxle8358 integrates line voltage and load compensation functions, and the system has excellent line voltage regulation and load regulation
