Hi

I am wondering if anyone has found a device that meets the following...

Device power min 2.1v or lower, max greater than 8.1v

Voltage input for conversion, max 8.1v, min as close to zero as possible.

Output 2.1v at circa 10mA.

This is for a small device powered from a set of super caps. Once charged, =
or partially so, it can startup but then run until the caps are drained. Th=
e device can be powered from the output once it is started.=20

Current plan is to use the caps in series. If I can find a suitable device,=
 the max input could be less than 8.1v if almost all the charge in the caps=
 can be used.

I have found some that get close but most have a min that is near 2v (1.8v =
for instance).

Thanks

Veronica
