Hello,
Datasheet 7.3.4 says “And then, the device will shut down after the UVP delay time (typically 14 μs) and re-start after the hiccup time.” Here, the hiccup time means tHiccupOn specified in 6.5?
Best regards,

Hi ,
Yes.
When the VFB voltage falls below the UVP threshold voltage, the UVP comparator detects it.The device will shut down after the UVP delay time (typically 14 μs) and re-start after the hiccup time (7 times of soft start time)----in 6.5 Electrical Characteristics session .

Hi Hirano,
The hiccup time means tHiccupoff, which is 7cycles.
Young, Vincent,
Thank you for your responses.
Let me confirm one thing.
Which is the “1 cycle”, 1/650KHz or Tss?
Best regards,
