Hello All,
I am making a USB power bank that will work with my Droid Turbo 2. I would like to have my power bank copy the specifications from the wall wart that came with my phone.
The wall wart specifications are;
5V, 2.85A
9V, 2.85A
12V, 2.15A
I was looking at copying the "USB Power Supply using TPS61088 to Support Quick Charge 2.0" reference design (PMP9773), and changing some values to match the wall wart. But I am having trouble figuring out the best options and values to get what I want.
Could someone help me figure out what value components would be my best option? I am not worried about small form factor since the case I am using holds 5 - 18650 batteries.
Thanks for any help
Anthony
