Low voltage Pic

[ruijc]

Hi all,

Just a quick question,

I'm currently working on a project that it would be better if supplyed with a 1,2V or 1,5V battery.

I've searched some pics and they all work with 2,5V and above.

Does microchip has any pic that can work with 1.2V ? If yes which one ?

Thanks

if you can not find one, then try using one of those tiny DC to DC converters.

1.5V to 5V or 1.5V to 6V.
As much as I know, tiny ones are good for 75mA.

Thanks alot sayzer

that can be a very good option

Do you have some references of those tiny DC to DC converters that i can start with ?

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.
