Other Parts Discussed in Thread: UCC28700, TPS2511
I am using the reference design exactly as it is presented, I had the PWBs fabricated, and have procured all of the parts as defined in your Bills of Material. I have built 4 sets of the USB charging cube and all 4 of them are doing the exact same thing. Each of them will charge the USB device for about a second, stop charging for about 3 to 10 seconds, and then repeat the cycle. I am not sure what to do, I was expecting that the circuit would power up and operate as defined.
What do I do next?
