摘要：8-Channels LED Driver CXLE81109B/C/L is an integrated power LED backlight driver that controls 8 channels of LED current for LCD backlight applications such as notebook computer and LCD monitor

The CXLE81109B/C/L is an integrated power LED backlight driver that controls 8 channels of LED current for LCD backlight applications such as notebook computer and LCD monitor. The CXLE81109B/C/L is a current mode boost converter integrated with 48V/2.5A power switch drivers the LED array. The CXLE81109B/C/L’s 8 channels of voltage controlled current sinks with current matching within 1.5%, which compensate for the non-uniformity effect of forward voltage variance in the LED stacks. To minimize the voltage headroom and power loss in the typical multi-strings operation, the CXLE81109B/C/L monitors the total highest LED forward voltage string and uses its feedback signal for output regulation. A SET pin is used for programming maximum LED current. A high contrast ratio true PWM dimming can be achieved by driving PWM pin with a PWM signal. LED current is proportional to the PWM pin duty. The CXLE81109B/C/L features extensive protection functions that include OLP, OCP, OVP and OTP. It is available in a TQFN4X4-24 & TSSOP-20 (FD) package.
