Hi, Team
Tss becomes 3msec when the customer connected Rmode=56kohm, Vfb=0.5996V. Could you please check the below waveform? I will recommend 53.6kohm, but we want to know the reason.
Best Regards,

Hi Satoshi,
The IC has only 4 soft-start timing (1ms, 2ms, 4ms and 8ms). For 4ms and 8ms, please follow the guideline 7.5.1.3.1 on page 18 datasheet carefully. Please also use 1% tolerance for Rmode.
