Cxle8275 is an internal integrated high-voltage power supply, two-way Buck Controller led PWM dimming color controller, suitable for 85vac ~ 265vac full range input voltage. Cxle8275 chip controls P1 and P2 pins by external PWM signal to realize PWM dimming and color matching function.
The cxle8275 chip works in the inductive current critical mode, and the output current does not change with the inductance and the LED working voltage, thus achieving excellent linear / load regulation. Cxle8275 has multiple protection functions, including LED open / short circuit protection
Protection, VCC under voltage protection, chip temperature overheat protection
