When I was using the lm5176, the following problems occurred (the output voltage was set to 24.6v):
1. When the input voltage was less than 27v, the chip would repeatedly attempt to restart but the startup failed.
2. When the input voltage was greater than 27v, it could start normally, but there were two abnormal startups before the normal startup, as shown in the related waveforms.
Please inform me of the cause of this situation and how to correct it.

The waveform diagram of the comp pin:
When the input voltage was less than 27v, the comp pin would repeatedly show the following waveforms and could not start normally:
