♠ Okokufaka kwe-TPS5433xA 4.5-V ukuya ku-28-V, Okokufaka okungu-3-A, Isiguquli Sesinyathelo-Phansi se-DC-DC esivumelanayo
Umndeni wamadivayisi we-TPS5433xA iziguquli ezivumelanisiwe ezinobubanzi be-input-voltage obungu-4.5 V ukuya ku-28 V. Lezi zixhobo zihlanganisa Le divayisi ine-FET ehlanganisiwe yohlangothi oluphansi eshintshayo eqeda isidingo se-diode yangaphandle enciphisa isibalo sezingxenye.
Ukusebenza kahle kukhuliswa ngama-MOSFET angu-128- mΩ kanye nama-84-mΩ ahlanganisiwe, i-IQ ephansi kanye nokweqa ukushaya kwenhliziyo emithwalweni elula. Ngokusebenzisa iphinikhodi yokunika amandla, amandla okunikezwayo okuvala shaqa ancishiswa abe ngu-2 μA. Lesi siguquli se-step-down (i-buck) sinikeza ukulawulwa okunembile kwemithwalo ehlukahlukene enereferensi ye-voltage elawulwa kahle engu-1.5% ngaphezu kwezinga lokushisa.
Umkhawulo wamanje womjikelezo womjikelezo ku-MOSFET yohlangothi oluphezulu uvikela umndeni we-TPS5433xA wamadivayisi ezimeni ezigcwele kakhulu futhi uthuthukiswa umkhawulo wamanje wokuthola uhlangothi oluphansi ovimbela ukubaleka kwamanje. Umkhawulo wamanje ozikayo oseceleni eliphansi uvala i-MOSFET yohlangothi oluphansi ukuze kuvinjwe amandla amanje ahlehlayo amaningi. Ukuvikelwa kwe-Hiccup kuqalwa uma isimo esidlulele siqhubeka isikhathi eside kunesikhathi esisethiwe. Ukuvalwa kwe-thermal kukhubaza idivayisi uma izinga lokushisa le-die lidlula umkhawulo futhi kunika idivayisi amandla futhi ngemva kwesikhathi se-thermal hiccup eyakhelwe ngaphakathi.
