+What happens when the output voltage is set to 3.3 V, and I hook it up to a 12 V battery?
+Which is better:
+   * The PSU pulls the voltage down to 3.3 V (or as close as possible until it hits the current limit)? or
+   * The PSU supplies zero current, letting the voltage float up to 12 V?

+Should have a 3.3v fixed output as well as the 5v.  Easy enough to handle.  1A should be good for most purposes on the fixed supplies.  Elektor ran a switching PSU module in April that I made some tweeks on and currently as waiting on boards. Galvanically isolating the adjustible supplies is a potential issue.  As soon as you hook a meter panel up, the two supplies are tied together. Hack around it by using two MCUs for A/D and transmitting to a third one via optoisolators?--pstemari
