Microcontrolled) CC/CV Power Supply Unit

It appears

one doesn't need no digipot nor DAC. PWM + RC-filter works pretty well

Voltage: is pretty linear until 1.25 which is XL4015 internal refence voltage value

Current: (output) per pwm is linear all the way but ADC has some non-linearity in lower ranges
