Lub TPS54140A ntaus ntawv yog 42-V, 1.5-A, kauj ruam-down regulator nrog ib tug integrated high-sab MOSFET.Tam sim no-hom tswj muab kev them nyiaj rau sab nraud yooj yim thiab hloov tau yooj yim ntawm kev xaiv.Qhov qis ripple-pulse hla hom txo qhov tsis muaj kev thauj khoom, tswj cov khoom tso tawm tam sim no mus rau 116 µA.Siv tus pin qhib, kaw cov khoom tam sim no raug txo rau 1.3 µA.
Undervoltage lockout yog teem rau sab hauv ntawm 2.5 V, tab sis tuaj yeem nce ntxiv siv tus pin pab.Qhov tso zis hluav taws xob pib qhov chaw nres tsheb yog tswj los ntawm tus pin pib qeeb uas tuaj yeem raug teeb tsa rau kev sib txuas / taug qab.Ib qho qhib qhov hluav taws xob zoo teeb liab qhia tias cov zis yog nyob rau hauv 94% mus rau 107% ntawm nws cov nominal voltage.
Ib qho kev hloov pauv dav dav tso cai rau kev ua haujlwm thiab cov khoom siv sab nraud kom zoo.Zaus quav rov qab thiab thermal shutdown tiv thaiv ib feem thaum muaj xwm txheej overload.
1. Leej twg yog cov neeg ua haujlwm hauv koj lub tuam tsev R & D?Koj qhov kev tsim nyog yog dab tsi?
-R & D Tus Thawj Coj: tsim lub tuam txhab cov phiaj xwm mus ntev R & D thiab tuav cov kev taw qhia ntawm kev tshawb fawb thiab kev loj hlob;Qhia thiab saib xyuas r&d department los siv lub tuam txhab r&d lub tswv yim thiab txhua xyoo R&D txoj kev npaj;Tswj kev txhim kho cov khoom lag luam thiab kho cov phiaj xwm;Teem cov khoom zoo tshaj plaws tshawb fawb thiab txhim kho pab pawg, tshawb xyuas thiab kev cob qhia txog cov neeg ua haujlwm.
R & D Tus Thawj Coj: ua cov khoom tshiab R & D txoj kev npaj thiab ua kom pom qhov ua tau ntawm txoj kev npaj;Saib xyuas thiab tswj qhov kev nce qib thiab ua haujlwm zoo ntawm r&d;Tshawb nrhiav kev tsim khoom tshiab thiab nthuav tawm cov kev daws teeb meem zoo raws li cov neeg siv khoom xav tau hauv ntau qhov chaw
R&d cov neeg ua haujlwm: sau thiab txheeb xyuas cov ntaub ntawv tseem ceeb;Computer programming;Ua cov kev sim, ntsuas thiab ntsuas;Npaj cov ntaub ntawv thiab khoom siv rau kev sim, kev sim thiab tshuaj xyuas;Sau cov ntaub ntawv ntsuas, ua cov lej thiab npaj cov kab kos;Ua cov ntawv tshawb fawb
2. Koj cov khoom tshawb fawb thiab kev tsim kho lub tswv yim yog dab tsi?
-Txoj kev xav thiab xaiv cov khoom lag luam lub tswv yim thiab kev ntsuam xyuas cov khoom txhais thiab cov phiaj xwm tsim thiab kev tsim cov khoom kuaj thiab kev siv tau tso rau kev lag luam
