Cxle8353 high efficiency non isolated step-down LED constant current driver chip with three section switch dimming functionsuitable for the non isolated step-down LED dimming power supply

Cxle8353 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. Cxle8353's dimming mode is simple and convenient. It only needs ordinary switches without additional dimmers.
The cxle8353 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, cxle8353 has the advantages of excellent load regulation rate and insensitivity to the change of inductance when it works in the inductive current critical mode.
The cxle8353 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.
Cxle8353 has a wide working voltage range and is suitable for AC input of 85vac ~ 265vac full voltage range. At the same time, the cxle8353 integrates multiple protection functions to ensure the stability and reliability of the system. Including LED open circuit and short circuit protection,
CS resistance short circuit protection, chip temperature intelligent control and chip power supply under voltage protection,
