Hello
We have troubles using the TPS54625.
At first use or after a few uses, the VREG5 pin becomes internaly short-circuited with the GND and the output voltage stay at 0. A short-circuit between the GND and the Vout can appear too.
The TSP54635 used to work perfectly on our PCB and this problem appeared only on our last batch.
