Need assistance to choose product

Hi!
I have following technical specification
1. Vin : 44-56V
2. Vout : 24-32V (tunable) Isolated from Input
3. Iout : 5Amp
4. over-load protection (at 5.25 Amp), over-voltage protection (at 60V) and output short circuit protection (at 5.5 Amp) with fold back characteristics.
5. efficiency = 85%
Please help me to choose a suitable switch on half bridge forward/LLC resonant/flyback topology. Any EVM from PI is appricable.
Thank you.

Thanks Neela
Would please suggest ICs from your product chain other than LLC like flyback or forward that can operate at low input voltage.
Thanks.
our parts normally has under votlage protection. it may not suit your design.
we don't have any IC directly works with your specs. if you choose LLC topology, HiperLCSxxx could be your choice, expect the VIn by default needs to be much higher for example 380V as typical, so integreated protection function will the ratioed according to pre-determined ratio.
over load and over current protection could be external circuits. tunable output will require a changing feedback pin resistor chain. over all, I don't think you have a direct fit from our products.
