DC1583A-B - LTC3625-1EDE Demo Board | VIN = 2.7V to 5.5V, VOUT= 4.5V or 4.0V @ IOUT up to 1A

Demonstration circuit 1583A is a 1A high effi ciency 2- Cell supercapacitor charger with automatic cell balancing featuring the LTC3625/LTC3625-1. The LTC3625/LTC3625-1 are step-up/step-down programmable supercapacitor chargers designed to charge two supercapacitors in series to a fi xed voltage of 5.3V or 4.8V (LTC3625), or 4.5V or 4.0V (LTC3625-1) from a 2.7V to 5.5V input supply. Automatic cell balancing is achieved during the charging phase, preventing overvoltage damage to either supercapacitor while maximizing charge rate.
