Noone had any advice about running Cyclone II based boards off rechargeable batteries? Is there something I dont know where it's a bad idea?
Buck and boost regulation just refers to whether the output voltage is lower or higher than the input voltage. So a buck regulator is still a switching regulator. For example, you could have a situation where your battery voltage is 3.6V and you have a boost regulator up to 5V and two buck regulators down to 3.3V and 1.2V.
I understand perfectly why you are concerned about getting a more complicated power supply design right first time. I chose to go the linear regulator approach so that I could concentrate on the FPGA operation and not worry if my powers supplies were causing problems. On the production version I might well substitute in switching regulators. You haven't mentioned whether you've looked at Linear Technology's switching regulators yet. I'm sure they are worth considering if you really only have one shot at the overall design. Now, was that Starbucks or Starboosts?:rolleyes:
