Hi guys,

I currently have a project with a device that will be running from a
battery. It will also have a USB port connected to one of the FTDI
chips. So what I`m looking for is a DC-DC converter that will take from
about 1.5v to 8v and provide me with a 3.3v output. If it can
automatically switch to battery power when the USB is unplugged that
would be great.

So far I`ve been looking at some chips from MAXIM, looks like the
MAX1700 could be suitable. Preferably I would like a plug in module with
everything on board, I can`t help but think somebody must sell these e.g
you put 1.5v to 8v in and get 3.3v out.


If anybody has any experience in this area I would be interested in your
advice.


Thanks again,
