TPS54302: about OFF TIME

Part Number: TPS54302

Hi,

I am considering the following specifications in TPS 54302.
The difference between VIN and VOUT is small, but is it OK?
I confirmed the data sheet, but I could not find the restriction of OFF TIME.
VINmin: 18.5 V
VINmax: 23 V
VOUT: 17 V
IOUT: 2.5 A

Best Regards,

    TPS54302 support 100% duty cycle as long as the BOOT to SW pin voltage is greater than 2.1V typically. For your off time, you mean the min off time or max duty that no skip and still work under fixed frequency, right? If like this, we need to do some lab test to verify this data.
