Hi, TI expert.
The following circuit is configured using TPS564201.
- DC-DC Block: 4A (13V → 5V)
If C299 (51pF, 50V-optional) is applied on the circuit, noise is generated, and if C299 is removed, the noise disappears.
Q1) Is there any problem with the circuit? Could you check the cause of the noise?
Q2)And, in the case of C299, it is optional, but is there any problem if I remove it?
If you have any data you need, please tell us.
Please check and answer.
