LTC3625 Datasheet (Linear Technology) - 1A High Efficiency 2-Cell Supercapacitor Charger

LTC3625, 1A High Efficiency 2-Cell Supercapacitor Charger

The LTC®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 maximizin
