Hello All,
Now I'm looking for a good way to power all the chips on the control board I'm designing. It will be powered by two rechargeable 9V batteries in series for a total input voltage of about ~14V.
The interesting thing is that the chips I am using all require a wide range of voltage inputs. I need to produce 1.8, 3.3, 5, and 12 volts for the different sections of my circuit. I was thinking about just slapping some linear regulators to make all the voltages but quickly realized that these would probably drain my batteries faster than the actual circuit would.
Sooo... I am looking into switching regulators since I know they are much more efficient. In a perfect world, I would like to see if there are any out there that can make all these voltages from one input (or at least some of them anyway). The other thing is I'm trying to find a one-chip solution so that I don't have to add a bunch of external support components. Has anyone here run into anything like this before?
Thanks,
Jason O
