Kev piav qhia
Lub TPS54320 yog ib tug tag nrho-featured 17-V, 3-Asynchronous kauj ruam-down converter uas yog optimized rau me me tsim los ntawm high efficiency thiab integrated high-sab thiab qis-sab MOSFETs.Ntxiv qhov chaw txuag tau ua tiav los ntawm kev tswj hwm tam sim no, uas txo cov khoom suav, thiab los ntawm
xaiv lub siab hloov zaus, txo hneev taw ntawm inductor.Qhov tso zis hluav taws xob pib qhov chaw nres tsheb yog tswj los ntawm SS / TR tus pin uas tso cai rau kev ua haujlwm raws li ib qho khoom siv hluav taws xob ib leeg lossis hauv cov xwm txheej taug qab.Lub hwj chim sequencing kuj tseem ua tau los ntawm kev teeb tsa kom raug thiab qhib qhov hluav taws xob zoo pins.Lub voj voog los ntawm lub voj voog tam sim no txwv nyob rau sab siab FET tiv thaiv cov cuab yeej hauv cov xwm txheej dhau los thiab tau txhim kho los ntawm qhov kev txwv qis qis tam sim no uas tiv thaiv kev khiav tawm tam sim no.Kev tiv thaiv Hiccup yog tshwm sim yog tias tus mob overcurrent tau txuas ntxiv mus ntev dua li lub sijhawm teem tseg.Thermal shutdown disables ib feem thaum tuag kub siab tshaj thermal shutdown kub.Lub TPS54320 muaj nyob rau hauv 14-pin, 3.5-mm × 3.5-mm VQFN, thermally enhanced pob.Device Cov ntaub ntawv PART NUMBER PACKAGE BODY SIZE (NOM) TPS54320 VQFN (14) 3.50 mm × 3.50 mm Rau tag nrho cov pob khoom muaj, saib Orderable addendum ntawm qhov kawg ntawm daim ntawv teev cov ntaub ntawv.
