4-Channel LED Backlight Converter with SMBus Controlled CXLE8165 is a high efficiency driver for 4 channels of LEDs. It’s a wide range input voltage operating from 6V to 24V.

The CXLE8165 is a high efficiency driver for 4 channels of LEDs. It’s a wide range input voltage operating from 6V to 24V. It’s capable of driving typically 68 (17x4) pieces of 3. 5V/180mA LEDs. It contains 4 channels of voltage controlled current sources with typical current matching of +1%. It’s built internal Rds(on) 0.25 ohm (typ.) with current mode control. The CXLE8165 be able to control LED current by SMBus interface. SMBus control LED current made had PWM, DC and Mixed-mode. The CXLE8165 has enable, shutdown function and Fault detection function. The CXLE8165 features extensive protection functions that include UVLO, Current limit, LED strings open and short circuit detections, Output Over-Voltage Protection (OVP) and Over Temperature Protection (OTP). The CXLE8165 is available in TDFN5x5-16 Packages.
