ANALOG DEVICES DC1583A-A

DC1583A-A is a demo board for the LTC3625 1A high-efficiency 2-cell supercapacitor charger with automatic cell balancing. The LTC3625 is programmable supercapacitor charger designed to charge two supercapacitors in series to a fixed voltage of 5.3V/4.8V (LTC3625). Automatic cell balancing is achieved during the charging phase, preventing overvoltage damage to either supercapacitor while maximizing charge rate. High efficiency, high charging current, low quiescent current and low minimum external parts count make the LTC3625 ideally suited for small form factor backup or high peak power systems. 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 enters a low current state, drawing less than 1μA from the supercapacitors.
