Cxle8328p cxle8328pc is a high-precision step-down LED constant current driver chip, which is suitable for the non isolated step-down LED constant current driver with 85vac ~ 265vac full range input voltage

Cxle8328p cxle8328pc chip is internally integrated with 500V power tube. It adopts patented drive and output detection mode. The working current of the chip is very low. It does not need auxiliary winding detection and power supply. It only needs a few peripheral devices to achieve excellent constant current output and linear adjustment rate, which greatly saves the system volume and cost. Cxle8328p cxle8328pc chip works in the critical continuous mode of inductance current, the output current does not change with the inductance and led working voltage, and achieves excellent load regulation rate. Cxle8328p cxle8328pc has multiple protection functions, including LED on / short circuit protection, hvdd under voltage protection, over temperature protection, etc.

Cxle8328p cxle8328pc is a high-precision step-down LED constant current driver chip, which is suitable for the non isolated step-down LED constant current driver with 85vac ~ 265vac full range input voltage
