Cxle8847 is a step-down constant current LED driver, which can work in dc8v to 36V input voltage range, low ripple, built-in power MOS, cxle8847 built-in fixed frequency oscillator and frequency compensation circuit, simplifying the circuit design.
PWM control loop can adjust the duty cycle from 0% to 100%. The built-in output over-current protection function reduces the switching frequency from 220khz to 60KHZ when the output is short circuited. Internal compensation module can reduce the number of peripheral components.
