In respond to JYHeli post of finding a LVBoost (or Step-Up DC Converter):
I search internet and found this:
The purpose of "HEX SCHMITT-TRIGGER INVERTERS" (74C14) is to generate frequency pulse. So, I modify it and use PIC12F629 to produce high frequency square wave( by simply generate ON and OFF on the output pins)
I also modify the NPN transistor (T1) and use MOSFET (IRFZ44N..which I have) instead. The purpose of this component is to turn on and off (like a switch).
The capacitor (C2) I use 10uF 100V. For the Inductor (L1), I don't have any so I use Align motor instead.
I tried it up on a breadboard with 4.2V (1S of LiPoly)....And I got 10Volt output!!
That mean, from 4.2V to 10V. The output voltage do have some spike (noise). With that, it is best the o/p is connected to a LM317 or LM338 or LM7805 voltage regulator instead.
So here u go... a simple Step-Up voltage regulator. I haven't test the o/p current it can produce. By looking at the design, how high the o/p current is depend on how thick the wire of the inductor and how high the oscillator frequency.
