Cxle8846 is a step-down constant current LED driver, which can work in the range of dc8v to 36V input voltage, with low ripple and built-in power MOS. Cxle8846 has built-in fixed frequency oscillator

Cxle8846 has built-in fixed frequency oscillator and frequency compensation circuit, which simplifies 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
