Hi,
I am currently testing the TPS563257EVM board with Vin =12V, Iout = 3A and I am experiencing a lot of noise when measuring the output voltage ripple with full bandwidth (350MHz).
In this document:
TPS563252 and TPS563257 Step-Down Converter Evaluation Module User's Guide (Rev. A) |
The output voltage ripple at 3A load, shows a cleaner output voltage ripple, in which I can observe the same waveform if I measure it with 20MHz bandwidth.
From the document:
I measured:
Can you please confirm that the waveform in the document is measured with 20MHz bandwidth?
