Hi everyone.
I'm brand new to this forum...so please excuse my ignorance a bit. Thanx!!!
I'm looking for a solar battery management solution to accommodate a micro project.
- I would like to harvest power from a small solar panel and output a regulated 5V stream to a mini external device.
- I would also like the solar panel to be able to charge and maintain a mini lithium battery.
- I would like the lithium battery to also output 5V to the external device as required (if solar current is low or not available)
- If solar NOR battery power is available to power the external device - I would like to be able draw power from a simple 5V USB port of a computer.
4.5-6V solar input (100-200mah)
5V 500mah USB input (typical of PCs and standard chargers)
3.7V 400-600mah single cell mini lithium battery
5-5.5V desired output (100+mah)
The catch is that I need the absolute smallest form factor circuitry - with the least amount of additional parts to make functional.
Size really is a major concern!
If anyone can make a recommendation it would be greatly apprecaited.
Thanx so much!
