Tool/software: WEBENCH® Design Tools
Hello Team,
Could you please give some insight into why there might be noise in this system. The issue was fixed by adding a 22uF cap at the connector output or at the load end.
My customer has provided 4 screenshots of the TPS54561QDPRRQ1 when operated at:
1. 30V input. Current ramp up from 0A to 6A. Noise stops around ~4A load.
2. 20V input. Current ramp up from 0A to 6A. Noise stops around ~3.5A load.
3. 10V input. Current ramp up from 0A to 6A.
4. 30V input. Current ramp down from 6A to 0A. Noise starts at ~1.9A.
Note: The design was pulled straight from Webench. I can send the schematic internally if requested.
Best,
Dajon McGill
