TPS25961: About the short circuit.

Part Number: TPS25961


Dear TI experts,

My client encountered the voltage short circuit problem of TPS25961 in the production project.

Measure the output voltage of U11 on the removed CAP PCBA round plate is 0.9V, and the output voltage of PCBA U11 with OK function is 5V. According to the schematic diagram, the normal output voltage of the U11 should be 5V.

                                                                   

                                                                                               

Can you help us find out why?
