Hi,
I have a requirement of supplying varying voltages from an incoming 24V DC source to an electromagnet. I need to derive 40V from 24V with about 2A output current requirment and dynamically change the output voltage from 40V to 12V in steps. Is there any I2C/SPI controllable buck-boost regulator? If not, is there a buck-boost converter whose feedback voltage can be changed using a DAC to change the output voltage from 40V to 12V in some discrete steps?
Regards,
