I am trying to build a current source that could deliver about 800mA current. It is meant for a battery Charger. I simulated the circuit for 70mA. Then I started to look for commercially available Current source ICs. Most ICs supplied not more than 10uA to 10mA. Is a current source of such high current capacity feseable?
And are current current mirroring circuits efficient? The theory says that the current in one branch is equal to the current in the other branch. So to get a 700mA constant current to the load, I have to drain down 700mA current. It seems a waste.
Please help.
Thank you.
