Other Parts Discussed in Thread: TPS25751
Tool/software:
We use TPS25750 for evaluation.
We wants to use TPS25750 for sink device(special specification charger).
This charger only allow 5V/1A and 20V/2A.
If we try to set 5V/1A and 20V/2A to Sink capability (Reg: 0x33).
But TPS25750 request 9V/2.22A to source.(AC adaptor(source) capability is 5V/3A, 9V/2.22A, 12V/1.5A)
Our expect is 5V/3A in this case.
Could you tell me how can we limit a input voltage in sink function?
