How to boost a sawtooth signal?
I need to make a sawtooth generator based on an NE555 (the power supply will be 15 volt - 5000mA), and I need to boost the output signal as follow:
Which needs to go from 9.6 volt to 14.10 volt with a 3000mA current.
I've found a schematich, but I don't know if is valid:
Would be a viable way, using this schematic, or there would be a better/different solution? If so, someone could suggest me another schematic or tell me how to modify the one which I posted?
