I am looking for DC to DC Buck converter with input voltage 12VDC to 50VDC and output range 12 VDC to 24VDC with 15A

another buck converter with input voltage 12VDC to 50VDC and output range 5 VDC, 12A

Your first converter input and output voltage ranges overlap. Do you need a buck-boost converter?

If it's buck-boost than better

if it's buck-boost than better but , I need three separate output 12VD, 24VD and 5VD with current ratting as specified above.

Is their any DC to DC converter like this?

Or we can use three different DC to DC converter .

So actually you need 12 - 50 V input with three outputs, 34 V @ 15 A, 12 V @15 A and 5 V @ 12 A, correct? I only show LM5119 interleaved for your 5 V solution, I'll have to check a different database for the other two.

I need 5 V @ 12 A, LM5119 reference design show 8A , if input range creating problem then we can reduce 12 - 50 V input to 12 - 40 V input

that reference design may specifically be for 8 A , bit that controller can do more.
