I am making a solar ipod charger with the maxim 756 chip. Any help with the circuit? Answered

I'm using the 756 chip to charge an internal 4.8v 600mA battery from a two 3v 6mA solar cells, which will in turn charge any device through USB. I figured this was the best way to charge at night, with no outlet, and no sunlight.


What did you make of the example circuits in the datasheet?


I know I'm using the basic 12v interface setup, but the rest is a bit fuzzy. I'm using a quad op amp to stop the chip from turning off when there is not enough power from the solar panel
