LT1738 minimum duty-cycle

Hi,

I am looking to use LT1738 in a SEPIC converter with a high step-down ratio and I was wondering what is the minimum switch duty cycle the driver is capable of ( provided the switch is capable) as only maximum is specified?

Slope Compensation graph on page 5 implies that it goes down to 0% but is this actualy true?

Many Thanks
