LM2731: LM2731XMF/NOPB

Part Number: LM2731

Hello everyone,

I was wondering if the LM2731XMF/NOPB can output a voltage higher than the 20V max if I reference ground to a higher voltage. Let's say I have 50V at Vin and a ground reference of 40V, would the device the the input as the differential (50-40 = 10V) and boost the voltage to 60V (20V above the ground reference 40V) or does it not work this way? I try simulating it and when I feed an input higher than 20V it will not boost but instead outputs what I have feeding the input. Please see below the configuration I have:

I would greatly appreciate your help.
