Voltage doubler waveforms
A voltage doubler is connected like this (the voltage source in series with the inductor simulates transformer output):
After stepping the load (100k, 1M, 10M, 100M, 1000M) the waveforms look like ...

How to 3x or 4x a DC voltage while minimizing board space with no microcontroller?
I have a 3.7V DC voltage source that I'd like to boost to at least 10 Volts.
I've been using Microchip's TC7660 component as a voltage doubler. But it only comes in SOIC (rather large for SMT). And ...
