I need to take unregulated li-ion voltage (3.3-4.2 V) and convert it to regulated DC around 6-12 V. The load is a 555 timer driving a component that needs 3V very-low-current AC.
The application is insanely space-constrained. At the most, there is room for a SOT-23 and two bypass capacitors, and that's it.
All of the boost regulators that I've seen require an inductor, three resistors, a capacitor, and a diode, not even including the bypass caps. There simply is not room for all of these external components.
Is there some circuit I can make, no matter how many corners need to be cut, that will let a boost regulator do its job "good enough" to drive a 555, without all these external components?
I'm guessing I don't really need the load-side bypass cap, so ditching that should make room for one other component.
