♠ TPS54302 4.5-V ukuya ku-28-V Okokufaka, 3-A Output, EMI-Friendly Synchronous Step-Down Converter
Idivayisi ye-TPS54302 iyibanga le-voltage engu-4.5-V ukuya ku-28-V, isiguquli sebhaka esivumelanisiwe esingu-3-A.Idivayisi ihlanganisa ama-FET amabili ahlanganisiwe ashintshayo, iluphu yangaphakathiisinxephezelo, kanye nesiqalo esithambile esingu-5-ms sokunciphisa isibalo sengxenye.
Ngokuhlanganisa ama-MOSFET kanye nokusebenzisa iphakheji ye-SOT-23, idivayisi ye-TPS54302 ifinyelela ukuminyana kwamandla aphezulu futhi inikeza indawo encane ku-PCB.
Ukusebenzisa i-Eco-mode ethuthukisiwe kukhulisa ukusebenza kahle kokulayisha ukukhanya futhi kunciphisa ukulahleka kwamandla.
Kudivayisi ye-TPS54302, ukusebenza kwe-spectrum yokusabalalisa imvamisa kwethulwa ukuze kuncishiswe i-EMI.
Umkhawulo wamanje womjikelezo womjikelezo kuzo zombili i-MOSFET yohlangothi oluphezulu uvikela isiguquli esimweni sokugcwala kakhulu futhi uthuthukiswa umkhawulo wamanje wamasondo amahhala we-MOSFET ovimbela ukubaleka kwamanje.Ukuvikelwa kwemodi ye-Hiccup kuqalwa uma isimo esidlulele siqhubeke isikhathi eside kunesikhathi samanje.
