    Hi Satoshi-san,

    There is no minimum off-time for these ICs. They will try to operate at 100% duty cycle. The only factor limiting pure 100% duty cycle operation is the voltage on the BOOT capacitor. If the BOOT-PH drops to the BOOT UVLO, the high-side FET will be forced off to allow the BOOT capacitor to recharge.

    Best Regards,
    Anthony
