Switch cap buck converter
Splet02. jun. 2016 · To regulate the voltage output of the buck converter just add a voltage divider to the output and have that read into the analog input pin of your micro-controller. SpletTake two capacitors C1 & C2 of equal capacitance. Charge C1 to say 10V. A basic formula relating charge and capacitance is V = kQ/C where V is capacitor voltage, k is a constant, Q is charge and C = capacitance. Now connect C2 to C1. The charge in C1 will now be shared equally between C1 & C2.
