Solar Charger

Portable energy for people on the move

With renewable energy high on the agenda, this little project will appeal to everyone who

would feel better charging their mobile or PDA from solar sources. A lithium-ion cell stores

the sunâ€™s energy in between charging sessions. Smart circuitry in the solar charger monitors

the battery voltage and protects the battery from overcharging and deep discharge.

Features:

Internal Lithium-Ion battery for storing solar energy

Versatile: your choice of batter and solar panel sizes
Direct charging/operation of USB devices.

Two switchable charging outlets:
- constant voltage output (5 V, max. 500mA)
- constant current (max. 150 mA)

Battery management for internal battery:
- Overload protection
- Under-voltage protection with hysteresis regulator and load dumping

Watchdog dropout protection

Compact dimensions
