The both MFG no mentioned above has same datasheet? In datasheet they have mentioned like there is a programming for the configuration. Link: https://www.monolithicpower.com/en/documentview/productdocument/index/version/2/document_type/Datasheet/lang/en/sku/MPQ8645P/document_id/4944/
Can anyone say, what is the exact difference between these.?
