Looking for a circuit designer who can design a circuit that will switch to battery when voltage from solar cell drops below 2.5 volts. Additionally output power must not exceed 3.3v. Input battery voltage will not exceed 3.6v and input from the solar panel will not exceed 6.6 volts. The device that this will feed will normally draw 0.5 – 1.5 mA with regular spikes to 15 mA. Maximum draw is 20mA. The specs on ...
