    From PIC Atmel328P battery powered with a maximum capacity of 4.5V and a minimum of 3.5V I have to operate a 12VDC valve. I have to charge a 4700uF electrolytic capacitor and then operate the valve with relays. At the moment I made a charge pump but it is very slow, it takes 2 minutes to bring the voltage to 12 volts from 3.5 volts. Anyone have a more efficient solution?
