Hello,
I am using the LM25085 in an application that has no load for a sustained amount of time (>16ms). I notice that during this time with no load, the device will switch at the designed frequency for about 250us, then turn off (no switching) for 500us. This is fine and it works in my application, but this behavior is not mentioned in the datasheet so I am curious if this is a designed feature or not. I have measured the R_t pin in case I was bringing the device into shutdown, but no such thing is happening.
Thanks,
John
