Inkcazelo ye-TPS53219A
Isixhobo se-TPS53219A sisilawuli esincinci esinobungakanani obuncinci kunye nolawulo lwe-D-CAPmode oluguqukayo.Isixhobo sifanelekile kwi-voltage ephantsi yokuphuma, yangoku ephezulu, umzila we-PC wamandla we-PC kunye nendawo efanayo yomthwalo (POL) unikezelo lwamandla kwiimveliso zabathengi bedijithali.Ipakethe encinci kunye ne-pin-count-count-count igcina indawo kwi-PCB, ngelixa i-EN pin ezinikeleyo kunye nokusetwa kwangaphambili okukhethiweyo kwenza kube lula uyilo lonikezelo lombane.Imowudi yokutsiba kwiimeko zomthwalo olula, abaqhubi besango abomeleleyo, kunye necala elisezantsi leFET RDS(on)imvakalelo yangoku ixhasa ilahleko ephantsi kunye nokusebenza kakuhle, phezu koluhlu olubanzi lomthwalo.Amandla ombane oguqulo (kwicala eliphezulu leFET yokutsalwa kwamandla ombane) luphakathi kwe-4.5 V kunye ne-25 V, kwaye uluhlu lwamandla ombane oluphumayo luphakathi kwe-0.6 V kunye ne-5.5 V. C ukuya +85°C.
1. Ngoobani abasebenzi kwisebe lakho le-R & D?Ziziphi iziqinisekiso zakho?
-R & D UMlawuli: yenza isicwangciso sexesha elide seR & D senkampani kwaye ubambe isikhokelo sophando kunye nophuhliso;Ukukhokela kunye nokulawula isebe le-r&d ukuphumeza isicwangciso se-r&d yenkampani kunye nesicwangciso sonyaka se-R&D;Lawula inkqubela phambili yophuhliso lwemveliso kwaye uhlengahlengise isicwangciso;Misela uphando lwemveliso egqwesileyo kunye neqela lophuhliso, uphicotho kunye noqeqesho olunxulumene nabasebenzi bobugcisa.
Umphathi we-R & D: yenza imveliso entsha ye-R & D isicwangciso kwaye ubonise ukwenzeka kwesicwangciso;Ukongamela kwaye ulawule inkqubela kunye nomgangatho womsebenzi we-r&d;Phanda ngophuhliso lwemveliso entsha kwaye ucebise izisombululo ezisebenzayo ngokweemfuno zabathengi kwiinkalo ezahlukeneyo
Abasebenzi be-R&d: ukuqokelela kunye nokusombulula iinkcukacha eziphambili;inkqubo yeKhompyutha;Ukuqhuba iimvavanyo, iimvavanyo kunye nohlalutyo;Lungisa izixhobo kunye nezixhobo zovavanyo, iimvavanyo kunye nohlalutyo;Ukurekhoda idatha yokulinganisa, yenza izibalo kwaye ulungiselele iitshathi;Yenza uphando lwamanani
2. Yintoni uphando lwakho lwemveliso kunye nombono wophuhliso?
-Umbono wemveliso kunye nokukhethwa kwemveliso kunye novavanyo lwenkcazo yemveliso kunye noyilo lwesicwangciso seprojekthi kunye novavanyo lwemveliso kunye nokuqinisekiswa kokuqaliswa kwintengiso
