Austria Microsystems has some nice little single cell step-up DC-DC converters with very low quiescent current. Here's a link to their AS1323 series.

Hey Tom,
It is interesting to think that the devices mentioned in the data sheet would operate under the 100ma limit. Would it be unusual to use more that one of these for discrete parts of the same circuit?

An IC like this requiring an inductor is new for me!!

Cool,

John

These are "switch mode converters". They are getting pretty common, though one that works well at such low voltages is a bit rare.

There are several new (with respect to North America) IC manufacturers in Switzerland and Austria. Some have levereged watch technology though I think this one isn't in that category. I've been seeing them advertising in the EE magazines over the last year or so.

Take a look at the Texas Instrument TL499. It supports an AC wall-wart and/or battery input and can switch between the two so you can essentially design a 'ups' into your device. Cheap too

Austria Microsystems has an ad in the latest EDN about "ultra-low dropout regultors". Relatively high precision (0.5%). Some with input-output differential as low as 70mv. Some with low quiescent current. Some with relatively high input voltage capability.

Interesting.
