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

Hi Davinder,
LM25180-Q1 isa good option. It has a 1.5A MOSFET integrated that allow your power requirements. For your schematic design, please use the Desing Tool calculator (link below).

Hi Shashank,
Please, use the Calculator Design tool for your design schematic (link below) as it is better than Webench. Vout zener diode is needed to clamp Vout voltage at no load conditions. LM25183 is a PSR Flyback converter that switches at a fsw_min…
HI Marco,
Yes, you can use LM25184 when 20 - 35 V (nominal = 28 V), Output Voltage = 28 V, Output current = 200 mA Max. The fsw_max for this converter will be 350kHz when working in DCM. You can get >80% for efficiency. Please, fill the calculator tool…
Hi Shuai,
Thank you for promoting our LM518x. I would recommend the LM25184. Pleas use our design calculator to help them design.

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?

Hi John,
Did you ever used our design calculator to help you design, which can be downloaded at the following link?

I just ran your numbers in, and the calculator showed it would not deliver 24Vout…
For a quick test, you can use the exiting transformer and you may see the load may be limited to slightly lower than 1A for 24V out under 24Vin, but you can see a lot of performances and it can give you some confidence to use the part. Ideally, you may…
A couple more tips.
Here's the calculator tool:

Also when testing the output voltage, could you check if there's a minimum load attached? The Zener diode won't clamp if there's no load.
