We designed an add on card with TPS5450 to supply a RPi 4 with 5V. We use 24V in.
Unfortunately the entire batch (1k) had to be replaced with off the shelf DC/DCs from China. We are now planning for the next batch and notice that the issue https://e2e.ti.com/support/power-management-group/power-management/f/power-management-forum/260390/tps5450-instability-outright-failure-certain-vin-voltages is marked RESOLVED. What exactly does "resolved" mean? Has the chip, or the recommended layout, been amended? If so, when?
