I am starting a project that needs a way to adjust a 9v supply to anywhere from 9v - 15v at 1.5A. The power is coming from 6 D cell batteries so the voltage will drop as the batteries wear down.
Does anyone have any schematics, pointers, or suggestions where I can look? I have browsed around Linear's website and found a couple chips that might work but don't have enough experience to be certain. I have built a couple switching supplies in the past, but I always followed a schematics in the datasheet.
After some browsing, this is the regulator I picked out. Will it work? http://www.linear.com/product/LT1377
Bonus: I also need to power a 3.3v micro-controller off the same set of batteries. If the circuit could also supply 3.3v that would reduce the overall number of components.
