The CXLE 8698 A is a continuous inductor current conduction mode step-down LED constant current driver for driving one or more LED strings. The CXLE8698A operating voltage is from 5V to 40V, providing adjustable output current, and the maximum output current can reach 1. 2A.
CXLE8698A built-in power switch tube, the use of high-end current detection circuit, DIM can support PWM signal dimming and analog dimming, brightness up to 65536 levels. CXLE8698A built-in over-temperature protection circuit, when the chip reaches the over-temperature protection point into over-temperature protection mode, the output current gradually decreased to improve system reliability
.
CXLE 8698 A circuit architecture enables no overshoot of the output current during low dropout operation and improves the working life of LED. The constant current circuit adopted by CXLE 8698A has excellent load regulation rate and linear regulation rate.
