Inkcazo
I-TPS54320 yi-17-V egcweleyo, i-3-Asynchronous step-down converter elungiselelwe uyilo oluncinci ngobuchule obuphezulu kunye ne-MOSFETs ehlangeneyo ephezulu kunye necala eliphantsi.Ugcino lwendawo olongezelelweyo lufezekiswa ngolawulo lwemowudi yangoku, ecutha ukubalwa kwecandelo, kwaye ngo
ukukhetha i-frequency switching frequency, ukunciphisa i-footprint ye-inductor.I-remp voltage start-up ramp ilawulwa yi-SS / TR pin evumela ukusebenza njengombane ozimeleyo okanye kwiimeko zokulandelela.Ulandelelwano lwamandla lunokwenzeka ngokuqwalasela ngokuchanekileyo i-ivumela kunye ne-drain evulekileyo yamandla izikhonkwane ezilungileyo.I-Cycle by cycle current limiting kwi-high-side FET ikhusela isixhobo kwiimeko ezigcwele kakhulu kwaye iphuculwe ngumda okhoyo wokukhangela ophantsi othintela ukubaleka kwangoku.Ukukhuselwa kwe-Hiccup kubangelwa ukuba imeko ye-overcurrent iqhubekile ixesha elide kunexesha elimiselweyo.Ukuvalwa kwe-Thermal kuyenza ingasebenzi indawo xa ubushushu bokufa bugqitha ubushushu bokuvalwa kwe-thermal.I-TPS54320 ifumaneka kwi-14-pin, 3.5-mm × 3.5-mm VQFN, iphakheji ephuculweyo ephuculweyo.Inkcazelo yeSixhobo INXENYE INOMBOLO YEPACKAGE YOMZIMBA SIZE (NOM) TPS54320 VQFN (14) 3.50 mm × 3.50 mm Ukubona zonke iipakethe ezikhoyo, bona iipakethe ezikhoyo isihlomelo esinokulandeleka ekupheleni kwephepha ledatha.
