Hey folks I need help on this would anyone know where I can get a D.C voltage doubler, voltage booster, D.C. step up, ect, that has a the ability to have a low voltage input 3.2VDC - 4.2VDC and produce an adjustable 6-9 VDC output rated between 2.5 & 3 amps? I'm new at this so my terminology may be wrong

And then my next question would be how would I build the circuit?

Any help would be appreciated

Thanks

Start here. Put in your specs.

Thanks that's kinda what I'm looking for but I'm actually looking for all the external components also, A plug and play package, I think I would fail miserably if I was to build that circuit

Google: DC-DC converters
Check the (US) Electronics vendors:
Digikey, Allied Electronics, Mouser, Newark Electronics, Jameco, MJPA, All Electronics

I missed the "adjustable". What is the source of the 3.4-4.2 V @ >6A

Click to expand...

The voltage source is (3) 3.7 lithium-ion batteries in parallel
The draw would be short lived approx 5-15 seconds on a random basis

I can see your problem now. It looks like those are going to be difficult parameters to meet in an off-the-shelf market.

Can't you just put the batteries in series when you are using them?

I have another thread on this forum pertaining to that, apparently not,
