XL6019 is a monolithic integrated circuit specially designed for boost and buck. It can work in the range of DC 5V to 40V input voltage, low ripple and built-in power MOS. XL6019 has built-in fixed frequency oscillator and frequency compensation circuit, which simplifies the circuit design. The PWM control loop can adjust the linear change of duty cycle from 0% to 90%. Built-in over-current protection function and EN foot logic level turn-off function.
