I have an application where the main power source needs to be a Alkaline AA battery (0.8V to 1.8V). So, I'll have a small boost converter to supply 3V to a cortex-m3 microcontroller.
The application needs to drive a small fan (20-60mm) that only needs to put out a very small CFM (<1.0cfm). Therefore, any fan that can reliably start at 3VDC should be sufficient.
I've played with a couple of 12VDC fans from ADDA that seem to start reliably at 4VDC, but 3VDC seems to be on the boarder.
So my question is, is there a fan out there with a very low starting voltage? Or am I really needing to bite the bullet and drop another boost converter on the board (not ideal)?
Thanks!
