FPGA super capacitor charge and discharge control circuit

ESD TVS electrostatic protection tube 0201 package 3.3V ultra low capacitance ESD

SMD aluminum electrolytic capacitor

Tantalum capacitor

Overview:
In this paper, several key technologies needed to apply supercapacitors are briefly introduced. Through simulation and physical verification, the 50% duty cycle of the inverter is used to match the step-down speed of the higher voltage with the boosting speed of the low-voltage capacitor. Reduce energy waste. The DC/DC charging and discharging module can realize fast and reliable charging and discharging of the ultracapacitor group, with large input power and reliable protection, and fully exerts the advantages of the super capacitor.
