Using the LT3652 solar battery charger designed by Linear Technology can be designed a very simple and efficiency solar battery charger circuit , using few external electronic parts .
LT3652 solar battery charger is a complete monolithic step-down battery charger which operates over a wide range input voltage ( 4.95V to 32V) .
The LT3652 solar battery charger provides a constant-current constant-voltage charge characteristic with maximum charge current externally programmable up to 2A. The desired output voltage can be up to 14.4V , programmed with a resistor divider .
This LM350 Car battery charger circuit project is a high performance charger that quickly charges gelled lead-acid batteries and turns off the charger process at full charge . This LM350 Car battery charger circuit will provide a charge current of 2A when the battery is nod fully charged , but as buttery voltage rise , current decreases .
This USB charger circuit is designed using the MAX1555 IC circuit manufactured by Maxim Semiconductor . This MAX1555 USB charger can be used using the USB power or AC power .
This MAX1555 charger is charging at 100mA from USB port and the maximum charging current increases to 350mA if the USB the AC adapter is connected . If both power types are connected in the same time the AC adapter is automatically given precedence.
This charger can be used for small devices like : PDAs ,Cell Phones , Digital Cameras , MP3 Players and other .
