Input DC Voltage to power supply

[bassmasta]

What would happen if, for example, you hooked a power supply directly to a dc source (eg car battery)?

 

[βeta]

Unspeakable things. You need an inverter.

Then it looks like I'll need an DC-DC converter (for this top secret project) with an input of 11-17V and an output 12V. Is that even possible?

 

[bassmasta]

I should have looked before I posted.

I'll look around for others, though.

Wait, what are you trying to do?

 

[bassmasta]

Run something 12V off of a 4 cell 14.8 lipo pack. 11V is the cutoff point, and fully charged cells are 4.2v x 4 = 16.8V.

*cough* wii *cough*

I don't know enough about the Wii to give you a definitive answer, but methinks it wouldn't like that. There's a TI part that would work but I forget what it's called.

 

[bassmasta]

It's not a Wii, but why wouldn't it like that?

 

[XCVG]

Electronics don't like overvolts. We know the Wii won't work undervolted to even 11.1V, so it's safe to assume that it's sensitive and wouldn't like an overvolt.

If it's not a Wii, what is it? It matters.

 

[bassmasta]

From the ripple voltage? It's for a, uh, high power device that requires 12v and 5v.

(I think it would be fine with a Wii though, because Palmer said the Wii runs on 14.8V.)
