I have found a set of sensors that I can control with either a single GPIO pin tied to all the chip enables, or via software - I haven't needed any external components.
My latest design uses the ISL91107IR buck/boost converter, however I am considering going back to just a straight LDO - my last rev used the NCP186A, which is not in your (awesome!) list:
Range voltage: 6 V Max
Max current out: 1 A
Quiescent current: 90 uA
Drop out voltage: 100 mV
Several things have made me rethink using the buck/boost:
- the ESP chip will actually operate at lower than 3.3V. I've heard people using as low as 2.8V to power them successfully. Most of my sensors are already using 1.8V and the ones that aren't can also operate with 3.0V or less
- when the input voltage drops below the threshold on the converter, the boost circuit draws more current to make up the voltage difference. On both solar and battery circuits the increased current draw pulls the supply voltage even lower, so you end up in a death spiral, and the increased current drains the power source even faster.
So in the end, it may work out you get better life by dropping your ESP supply voltage to to 3V or even 2.8V if you can, and using a normal high performance LDO instead.
I need to do some more experimenting...
