Supercapacitor charger electronic circuit using LTC3625

A very simple supercapacitor charger electronic project can be designed using the LTC3625 IC designed by Linear technology to charge two supercapacitors in series to a fixed output voltage (4. 8V/5. 3V or 4V/4. 5V selectable) from a 2. 7V to 5. 5V input supply. Automatic cell balancing prevents overvoltage damage to either supercapacitor while maximizi

ng charge rate without using any balancing resistors. This electronic circuit project presented in this circuit diagram has high efficiency, high charging current, low quiescent current and require low minimum external parts Charging current/maximum input current level is programmed with an external resistor. When the input supply is removed and/or the EN pin is low, the LTC3625 automatically enter a low current state, drawing less than 1 A. The circuit is very simple requiring few external electronic parts, excepting the LTC3625 IC and solar panel this circuit project require a LT1784 op amp and some common external parts.
