Hello Team,
Could you please answer my customer question.
in the end every single step moving to your suggested reference design were a little improvement till it works better, but one big mistake was the usage of the sync input with a frequency modulation.
With our sync signal it was not possible to draw high currents. I saw that the dither signal modulation of the LM5175 is 5%, but our sync chip signal modulation is 10%.
In the datasheet of the LM5175 is no specification which specify the highest allowed modulation value on the sync input. Do you have any further information for us?
However, I removed the sync signals from both LM5175s and run them standalone with the activated dither function, but it would be nice to try and use it in the future
Thank you in advance.
Best,
Needhu
