Hi all,
I am looking for an LED Driver IC (or a discrete circuit) that can power 8 to 16 white and 8-16 UV 5mm LEDs from 2 AA batteries (switching between the two sets). My main constraint is that the IC should be in a DIP package, not surface mount. Size is not that important. I could get something like the MicroPuck, but I prefer to build the circuit myself to learn more about boost converters.
I've looked at some manufacturers but most all of these are in SMT packages. Found a couple from Maxim-IC, the MAX633, MAX643 and the dual MAX743 I might be able to use.
A circuit or chip with a low battery indicator output would be a plus.
TIA
