I want a circuit and also a gerber file of such a system. I know it maybe very simple for you, but still i can't find what i need elsewhere. Input will be a PV system of maximum voltage of 14 Volts and 6 Amps current. I want the output of the stablizer to be around 84 Watts, meaning about 25 Volts and about 4-5 Amps. I want the circuit to be done using a controller (IC) of somekind and not by the old analog way. The most important aspect of this job though is that I absolutely need the PCB to be very small, at around 4x4cm.
