#134960 - Use both? Responding to: ???'s previous message |
If cost is not a problem, you may find that the best solution uses two regulators, and switcher and a linear. The micro could run on a either regulator using diodes, and in sleep mode the switcher can be disabled. The high power loads would be connected to the switcher, which would be enabled and disabled by the micro.
Why are you using a 9V battery? I would have thought a 4.2V battery might make your life easier. There are some really good single cell solutions around, and buck-boost converters let you step up or down . |
