Mar 3, 2013 at 22:15 comment added Sam 1. I could, but would the 9v last as long without some kind of regulation? Do you think I would be better off just using a higher resistance? I am trying to make this device work for as long as possible on one battery. So do you think it would lose less power with a higher resistance and no switch mode converter. Or a lower resistance with the switch mode converter? 2. Would a buck converter work better than the LM25576 mentioned above? Thanks.
