    Manjesh, I recommend LM25184 , which is a 42VIN with a 65V/ 4.2A integrated MOSFET that will allow you to deliver the required power with a VIN_nom=24V. Please, use the Calcualtor Design to design your schematic/BOM. Link is below. Thank you LM25183-LM25184DESIGN…

    Hi Eyal, I think this is possible, but, the voltage stress you would be exerting on the device is VIN + abs(VOUT1,2) = 39V. The device can only operate to 36V max. Could you consider a flyback design for this application? https://www.ti.com/product/L…
