I have issues with the TPS54231 in a new version of my boards. Hundreds of the previous version worked flawlessly.
What changed? As far as I can tell only the color of the silk screen from green to white! I would need some help for debugging, maybe a wrong cap somewhere?
I use the 5V design basically 100% as layed out in the datasheet, 12V in. Following some screen from the PH pin, overview and close-up. No load, should actually run in eco mode.
Thankful for any pointer or further investigation points,
Bernd
