Hi,

If AutoNgt is set to 0, TPS65988 will select first PDO of the source's PDO list for the contract. If AutoNgt is set to 1, TPS65988 will look for a PDO in the source's PDO list that satisfy TPS65988's sink capability.

Regards.

Hi Tommy,

You mean,

if source PDO is 5V/3A, 9V/3A,15V/3A

if AutoNgt is set to 0, 988 will seltec 5V/3A.

if AutoNgt is set to 1, 988 will select sink cab (15/3A), which mean the result is 15V/3A

Am I correct?
