LTC3625/LT1784 Solar Powered Super Capacitor Charger with MPPT

Oct 26th 2000
The input of the LTC3625 can also be driven by many widely available solar cells. In this circuit, MPPT (maximum power point tracking) is implemented by modulating the charge current based on the input voltage of the LTC3625. The LTC3625/LTC3625-1 are programmable supercapacitor chargers designed to charge two supercapacitors ...
