Customer ServiceThe maximum voltage of a single layer super capacitor is typically 2.7 V, which leads to a usable capacitor voltage range of 1.9 V to 2.7 V.

The circuit uses SUPER CAPACITORS, as opposed to batteries. Super capacitors are like other capacitors, only they have enormous power storage capabilities. Capacitors have two storage variables: Maximum charging voltage and capacitance (Measured in Farads). Capacitance is a measure of how much energy can be stored in a capacitor.
Most super capacitors (supercaps) can be discharged down to 0 V and recharged to their maximum voltage with the manufacturer recommended charge current. A simple voltage regulating LED driver with constant current, usually regulated by sensing a low side, series current sense resistor, then a voltage clamp can be used to charge a super capacitor.
A super capacitor normally has a capacitance of between 1 to 3000 farads, which make them good substitutes for batteries! We are going to safely charge 2x 400 farad capacitors in series up to 5.4VDC, and feed that voltage through a DC-DC booster circuit.
Supercapacitor Charging Basics Charging a supercap is similar to charging a battery except for a couple of key points. The first is that a completely discharged capacitor can be charged at full current for the whole charge cycle, whereas a battery needs to be trickle charged until the battery reaches a specified minimum voltage.
Eventually, the super capacitor voltage, and therefore the charging circuit’s operating efficiency, increases so the capacitor charges at the desired constant (fast or max) charge current, ICHG, until it reaches and remains at constant voltage (CV) regulation voltage, VREG.
