I imagine it's tricky to get 12V out of 11V (say)
whilst able
to deliver enough current to keep a disk spinning (say). Of
course I'm sure it's been done, I've just not seen published
details of schematics etc. anywhere before!
The topology you're looking for is SEPIC, single-ended primary
inductance converter. With a SEPIC convertor the input voltage
range can overlap the output voltage.
Cheers,
Lee.
