I want to make a variable power supply controlled by a microcontroller (stm32f767zi).
The input voltage will be 24V. The output voltage should be adjustable (via the microcontroller) between 14V and 31V.
The output current is maximum 0.8A.
Can I use LTC3115 or other IC from Linear Technology and how can I adjust the output voltage via the microcontroller (DAC,...)?
