♠ TPS54388C-Q1 Izimoto 2.95-V to 6-V, 3-A , 2-MHz Synchronous Buck Converter
Idivayisi ye-TPS54388C-Q1 iyisici esigcwele esingu-6-V, 3-A, isiguquli semodi yamanje eyehlayo ehambisanayo enama-MOSFET amabili ahlanganisiwe.
Idivayisi ye-TPS54388C-Q1 inika amandla imiklamo emincane ngokuhlanganisa ama-MOSFET, isebenzisa ukulawula kwemodi yamanje ukuze kuncishiswe isibalo sezingxenye zangaphandle, ukunciphisa usayizi we-inductor ngokunika amandla kufika ku-2-MHz ukushintsha imvamisa, nokunciphisa unyawo lwe-IC nge-3-mm × 3 encane. -mm iphakheji ye-QFN ethuthukisiwe ngokushisa.
Idivayisi ye-TPS54388C-Q1 inikeza ukulawulwa okunembile kwemithwalo ehlukahlukene enereferensi ye-voltage engu-±1% enembile (Vref) ngaphezu kwezinga lokushisa.
Ama-MOSFET angu-12-mΩ ahlanganisiwe kanye nama-515-μA avamile okunikezwayo akhulisa ukusebenza kahle.Ukufaka imodi yokuvala shaqa usebenzisa iphinikhodi yokunika amandla kunciphisa ukunikezwa kokuvala shaqa ku-5.5 µA, okujwayelekile.
Isethingi yokukhiya i-undervoltage yangaphakathi iku-2.45 V, kodwa ukuhlela i-threshold ngenethiwekhi ephikisayo kuphini lokunika amandla kungakhuphula isilungiselelo.Iphinikhodi yokuqalisa kancane isetha irempu yokuqalisa i-output-voltage.Isiginali yamandla avulekile edonsa amanzi ikhombisa lapho okukhiphayo kungaphakathi kuka-93% kuya ku-107% wevolthi yayo yokulinganisa.
Ukugoqa imvamisa nokuvalwa kwe-thermal kuvikela idivayisi ngesikhathi sesimo esidlulele.
