Hi All,
We've got a HP Specter DA0X36MBAE0 REV: E in last week with a no power no charge light presentation. Device at first would pull 20V .6A and you could see the TPS 65988CE getting quite hot. But before I could complete checking all USB C ports and both sides of the cable it seems like the TPS has died out as now I'm only getting 5V .2A. I found there was a short on most of the caps around the TPS so I decided to remove it and retest which removed the short.
I've done some googling and have found a lot of people posting about this chip and after they replaced it the system still did not power on, and there seems to be some uncertainty as to whether the TPS65988CE requires programming or not. Has this been discovered yet?
Also how do you differentiate between the variants of the TPS65988? It seems like there are 3 variants, but it seems like all 3 have different datasheets and they all have the same package type/size so I'm having difficulty differentiating between the variants. Ali Express seems to be the only one listing them as TPS65988CE, id rather order them from digikey or even better someone locally like RS components or element 14 if I can but there labeling them as TPS65988 DH,DK,or DJ, RSHR.
Thanks for the assistance.
