I could not find reference design for 48V 2Amp based on LM5116 or similar
VIN = 40-100V
VOUT = 35V regulated
Iout = 1Amp (typ) may goes to 2Amp surge for a period of time.
I scanned your TI but no reference design (unlike LTC).
LM5116 look like good solution but no proof it work reliably.
I suffered issue
(a) Webench provide incorrect compensation calculation (not same result as in excel). It shown to be unstable until I switch comp circuit to excel method and it work better but, when I raised VIN voltage from 50V to 65V, it blow up transistor and IC.
(b) I have evaluated TI board with LM5116, it keep blowing up MOSFET and TI device when I raised VIN voltage to 65V and VOUT= 35V.
