Short circuit protection on boost dc/dc converter LT1680 based

This evaluation board generates 48Vout from 12Vin.

Boost topology cannot provide short circuit protection. If short circuit protection is a must, check out LT8390, a 4-Switch Buck-Boost controller.

Hi W.G.

Many Thanks for the suggestion,

I think that for my project I will use LT8390,

I downloaded the simulation file LT8390_DC2431A of evaluation board from from site and I modified the feedback resistor and current sense resistor value to obtain 48V max 5A, also I changed the mosfets with 2 millohms 60 V VDS models, but maybe I can leave in input models with 1 milliohms and 25V on VDS?

Any other suggestions?

I attach the simulation schematic

Best Regards
