Other Parts Discussed in Thread: LM61495
When the LM61495 input is powered down, the output voltage has a jitter problem, as shown in the figure below.
Customer is testing with a electronic load : OK with a load below 4A, it will jitter with a load above 5A.
The demo board also has this problem.
There is nothing adjustable on the SCH, please help to see where the problem is?
Fsw is 400KHz and the output inductor is changing to 2.2uH
