Hi,
I have an project where I have to control a power supply using a processor. I was wondering if the following would work?
The power supply I have to control is a DC 12v (11.3v will work) , running at 600ma when 12v. I have to change the voltage from 12v to 3v at different intervals. I thought of using a 2A NPN transistor with emitter following. I will have a d/a convertor which will produce 0-5v, which goes into an opamp and converts to 0-12v . Would this work?
I have attached a drwing of what I though might work, and the pdf of the npn I was planning to use. Any help would be appreciated.
Many Thanks
Scott
