Hi! I need a voltage divider that I can program by software to obtain subvoltages of my 12V 2A power supply. Is it possible?Thanks in advance!
If the output terminal (connected to a load) needs to be a constant voltage, then everything should be ok if the load draws very little current (when compared with the source current).
But if you need an output voltage where output current is a significant amount, then you'd need to focus on a programmable variable voltage power supply.
