Description XL6019 is a boost constant current LED driver, can work in DC5V to 40V input voltage range, low ripple, built-in power MOS. XL6013 fixed frequency internal oscillator frequency compensation circuit simplifies circuit design. When the input voltage is greater than or equal to 12V, XL6019 can drive 5-10 string 1W LED. PWM control loop can adjust the duty cycle varies linearly from 0 to 90%. Built-in over-current protection with EN pin logic-level shutdown. Internal compensation module can reduce the number of external components.
