LT8310 Output Current Threeshold in Different İnput Voltages

Category: Hardware
Product Number: LT8310

Hello, 

I am designing Forward Converter. My input 9-50V and my output 12V, 1A. I am using LT8310 as a controller. But in different input voltages my output current threeshold is changing. For example, when input voltage is 12V overcurrent limit is 750mA and my input voltage is 45V overcurrent limit is 1.2A. My nominal voltage is 28V. With LT8310 I can't get fixed overcurrent threeshold? Can you please inform me?

Edit Notes

Note: LT8310 configured to current mode, ı use opto coupler feedback. My reference programmable reference is LT1431, my opto coupler is MOC207.
