Hullo again all- today I am again in need of some experience. I have been trying to find a preferably integrated solution that can step up both voltage and current? I am definatly not familiar with building power supplies but have been doing quite a bit of reading about it and also looking at various manufacturer offerings- I am hoping that someone can guide me better than I have been doing!
I need to step up a N-cell or those rough specs- 1.2vdc @ ?mA to about 3.6vdc @~300mA or better. I also am looking for a better battery choice- should be rechargable and at least as small as an n-cell. If I could find one at 3.3-3.6vdc 300-500mA then I would be in great shape, but haven't been able to find anything that small...
Am I being unrealistic here? Any advicewould be appreciated, I can provide additional info if needed, but must say that alot of the parts I am using are salvaged, like ir leds so I don't know much about them, which is also causing some headaches....
The solution I need has to be as small as they get, the pcb itself is only 21 x 19mm and is already packed, I was thinking about making the pow supply a tiny plug-in in series with the batt leads, like a micro dongle or something? I dunno, I just was farting around with the pcb layout late last night and it is increasingly obvious that there are to many parts and not enough space, so I may need to cut back on a couple of functs still...
thanks in advance--!me
