Hello
I have a device (a printer) which will work on 7.2V and requires about 2.5 amps. I need to design a circuit that will supply the voltage only when required. Hence i decided to use a transistor for the switching. I am not too sure which transistor to use. Can anybody kindly suggest me the option for the same. Or for that matter, will a simple switching circuit actually work for this configuration?
How about using TIP31.
Datasheet of TIP31 : http://www.fairchildsemi.com/ds/TI/TIP31A.pdf
I need to switch it via controller which works on 3.3V. ie. High will be 3.3V max.
Your advice will be very helpful.
