Low voltage Pic

ruijc, Try a MAX1724. I use them all of the time. Good upconvertor.....

Thanks Dave,

I've checked these converters and they look very good

One question though...
Do we really need the coil for it to work ?

thanks

ruijc,

Check Figure7 on MAX1724 datasheet. You can adjust the output voltage.

Nice chip Dave.

Yes...i did see that

nice idea indeed. This is a good solution that i will test

My question now is about that 10uH coil...can i live without it ?

I need as less componets as possible and no coils if possible.

The inductance provided by a coil is at the heart of most boost converter (as well as buck and flyback topologies). So, the answer is no, you can't live without it, at least not with this application.
Although, if you do some searching, you'll find suitable coils with very small dimensions.
