Hello,
The compare function does not show any differences: http://www.ti.com/assets/js/compareParts/compare.html?familyId=3391&parts=TPS65988DJ,TPS65988&cols=o1,p1694,p404,p3108,p2983,p3109,p3110,p3111,p3112,p386typ,p3244,p3245,p365,p1192&lang=en
In the packaging information, only the device markings are different.
There seems to be no difference in the pin assignments either.
Can you please share the difference/s between the two parts?
Thank you,
Elisha
