Cxle8354d high efficiency non isolated step-down LED constant current driver chip suitable for the non isolated step-down LED constant current driver power supply of 85vac~265vac full voltage input range

The cxle8354d 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, cxle8354d works in the inductive current critical mode of peak current off and zero current on. The LED output current does not change with the change of inductance and LED output voltage, so it has the advantages of excellent load adjustment rate and insensitive to the change of inductance.
The cxle8354d 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.
Cxle8354d has a wide working voltage range and is suitable for AC input of 85vac ~ 265vac full voltage range. At the same time, cxle8354d integrates multiple protection functions to ensure the stability and reliability of the system. Including LED open circuit, short circuit protection, CS resistance short circuit protection, chip temperature intelligent control and chip power supply undervoltage protection.
