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. https://www.mouser.com/catalog/specsheets/xppower_06192019_DS_STH05_170519.pdf https://www.mouser.co.uk/ProductDetail/XP-Power/STH0548S05?qs=PzGy0jfpSMvu3ftBUxiygQ== Please refrain from editing posts, unless it's just to correct a typo or spelling error. Posting a follow-up would have been better, as it would push the thread back to the top and increase the chances of a helpful response. |

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/ |
