[SOLVED] general question about LED driver for electric torch

[gone]

hi all,

i am currently working on a project which is about LED driver for electric torch, it's very common that we use battery supply in this application, and in my project i chose to use a 2A chargeable battery...

but when i am designing the feedback for the driver, i use 3V- 0 range for all the components which are amplifiers / comparators, latch and so forth.....

i am wondering how can an electric torch have a 3V supply if i just use a 2A battery

it's important to me because i have to fabricate the real product for my project

thanks

What battery, exactly, are you using? Is it lithium ion?

Your question does not make sense to me.
