Kev piav qhia rau TPS630250
Lub TPS63025x yog kev ua haujlwm siab, tsis tshua muaj quiescent tam sim no buck-boost converters haum rau daim ntawv thov qhov twg cov input voltage siab dua los yog qis dua cov zis.Cov zis tam sim no tuaj yeem mus siab li 2 A hauv kev txhawb nqa thiab siab li 4 A hauv hom phaw.Qhov siab tshaj plaws nruab nrab tam sim no nyob rau hauv cov keyboards yog txwv rau ib tug raug tus nqi ntawm 4 A. Lub TPS63025x tswj cov zis voltage tshaj qhov ua tiav input voltage ntau los ntawm kev hloov pauv ntawm puck lossis boost hom nyob ntawm qhov input voltage kom muaj kev sib hloov ntawm cov qauv.Lub pulse-boost converter yog raws li nyob rau hauv ib tug taag zaus, mem tes-dav-modulation (PWM) maub los siv synchronous rectification kom tau zoo tshaj plaws.Thaum tsis tshua muaj load tam sim no, lub converter nkag mus rau lub Hwj Chim Txuag hom kom muaj kev ua haujlwm siab tshaj qhov ua tiav cov khoom tam sim no.Muaj PFM / PWM tus pin uas tso cai rau tus neeg siv xaiv ntawm kev ua haujlwm tsis siv neeg PFM / PWM hom thiab yuam PWM ua haujlwm.Thaum lub sij hawm PWM hom kev ruaj khov ntawm feem ntau 2.5 MHz yog siv.Cov zis hluav taws xob yog programmable siv lub tshuab hluav taws xob sab nraud, lossis yog tsau sab hauv ntawm lub nti.Lub converter tuaj yeem raug kaw kom txo qis roj teeb.Thaum lub sij hawm kaw, lub load yog disconnected ntawm lub roj teeb.Cov cuab yeej tau ntim rau hauv 20-pin WCSP pob ntsuas 1.766 mm × 2.086mm thiab 14-pin HotRod pob ntsuas 2.5 mm × 3mm.
