Hi,
Look at the following link:

I'm giong to use it for my supercapacitor powerd torch gadget .... if I can
get hold of it ...
Cheers

To step-up a single-cell 1.5v battery to ~3.3v, is there a better option
than using a boost regulator like an LM2623?
(http://www.national.com/ds.cgi/LM/LM2623.pdf)
I'm trying to hack out power options for a simple battery-operated LED
gizmo, and it's turning out more complex than the gadget itself.
BTW, load is 1mA to ~100mA depending on LED duty cycle, with a lot of
"off" time. (The power needs to stay on, but the microcontroller will be
quiescent - I'm not sure that a simple transistor+inductor scheme will
give much battery life.)
Thanks!
Richard
