LM2576: Step Down regulator with 60V input and output 2 amp

Hello
Step Down regulator with 60V input and output 2 amp.
1- We use IC Lm2576HV. Is there another IC that has better quality and less output noise?
We need an IC with an input of 9 to 60 volts for a 5 volt fixed output with 2 amps.for example; we used 24v in with 5v 2A out and 60v in with 5v 0.5A out.
2- Can we say that the LM2576-5V-fix is better than LM2576-Adj for a constant 5V output? Is there less noise and better quality because the air LM2576-5V-fix does not need feedback resistance?

Hi Reza,

Pls try latest LMR16020 60V 2A buck regulator.

Fixed output version has internal feedback resistor for less part count and little better noise immunity.

Hello
Thanks for your reply
Can you introduce another IC with 3 amps or 5 amps?
Step Down. Input 9 to 60 or 90 volts. SMD.
But it is not a package of QFN or VQFN. This means that the pin of IC are not under the body.
