Cxle8361 is a high power factor non isolated step-down LED constant current driver chip. The chip integrates a single-stage active power factor correction circuit, which is especially suitable

Cxle8361 integrates a single-stage active power factor correction circuit. The system can achieve high power factor and low total harmonic distortion of input current. Cxle8361 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, improves the system efficiency, and improves the EMI characteristics of the system.
Cxle8361 adopts the proprietary closed-loop feedback control technology. The chip can work in two ways: floating and field, and can achieve high-precision LED constant current output. Cxle8361 integrates line voltage and load compensation functions, and the system has excellent line voltage regulation and load regulation.

Cxle8361 is a high power factor non isolated step-down LED constant current driver chip. The chip integrates a single-stage active power factor correction circuit, which is especially suitable
