    VOUT, IVIN < 1ВµA in Shutdow Low Profile 12-lead 3mm Г— 4mm DFN Package The LTCВ®3625/LTC3625-1 are programmable supercapacitor chargers designed 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 maximizing charge rate. No balancing
    resistors are required. n Applications High efficiency, high charging current, low quiescent current and low minimum external parts count (one inductor, ...
