current limiting PS and PIC

I am looking to design a current limited, 2-6A, power supply controlled by a PIC. Consumer electronic "smart microprocessor" battery chargers seem to know how to regulate the current.

Any thoughts?

I am trying to remember if there was an explanation of the linear version of a foldback current regulator in Horowitz & Hill. Adding a microprocessor control to that should not be too difficult. You should, however, look quite closely at the consequences of losing control of the voltage and current outputs. You will need to make sure that you know, should the microprocessor suddenly halt with a fault, the outputs attain a safe state (most likely off).
