28V to 5V buck, 300mA, automotive aftermarket

Dear Mates,

what would you suggest for a buck converter from 28V to 5V @ 300mA output, very few requirements: internal feedback and enable

Litte update, sorry, my requirements were terrible.

This product will be used in chassis level, supplied by KL30 and KL15 lines.

Its mandatory to have input tolerance up to 60V during 1min, although the device is not required to work.

I was thinking something very common, like LM2xxx something or similar.

Either I missed the part about 60V or you edited it in later. There are plenty of DC:DC converters which can take up to 60V in.

Why not make your own?
Plenty of cheap ICs with good schematics : https://www.digikey.com/short/pn1591

for example mpq2459  https://www.monolithicpower.com/en/mpq2459-aec1.html

Here's datasheet, see page 10-12  : https://www.monolithicpower.com/en/documentview/productdocument/index/version/2/document_type/Datasheet/lang/en/sku/MPQ2459-AEC1/document_id/3888/
