Hi,
I’m designing a power bank with the following features:
- Input: 5VDC/2A wall power supply
- Battery: 1 Li-Ion Cell
- Output:
a) Input is present: the output should charge the connected device to 2 Amps max. If output current drops it should start charging the internal battery (output priority).
b) Input is not present: the output should be 5V 4 Amps max (battery boost)
Could you recommend a part that can meet these requeriments?
Sorry, there are too many parts, I’m a little lost.
Thank you
