Maximum Duty Cycle for LT8301

We are planning to use LT8301 for generating 28V, 50mA isolated power supply. Input voltage range is 6V to 32V. 


1) Considering 1:2 transformer and 6V input voltage, duty cycle will be ~70%. Is there any maximum duty cycle limit for LT8301 or similar no opto Flyback converters?


Duty Cycle Vs Input Voltage



2) We are using this power supply in energy sensitive application. Is there any alternate parts/solutions for achieving high efficiency over minimum and maximum loads?


Thanks & Regards,
