Inkcazelo ye-LM53603-Q1
I-LM53603-Q1, i-LM53602-Q1 i-buck regulators yenzelwe ngokukodwa usetyenziso lweemoto, inika i-voltage ephumayo ye-5 V okanye i-3.3 V (kunye ne-ADJ inketho) kwi-3 A okanye i-2 A, ukusuka kwi-voltage yegalelo ukuya kwi-36 V. Advanced i-high-speed circuitry ivumela isixhobo ukuba silawule ukusuka kwigalelo ukuya kwi-20 V, ngelixa libonelela ngemveliso ye-5 V kwi-frequency switching ye-2.1 MHz.I-architecture entsha ivumela isixhobo ukuba silawule i-3.3 V ye-voltage ye-input voltage kuphela ye-3.5 V. Zonke iinkalo zalo mveliso zilungiselelwe umthengi weemoto.Uluhlu lwegalelo lombane ukuya kuthi ga kwi-36 V, kunye nokunyamezela okwethutyana ukuya kuthi ga kwi-42 V, kunciphisa uyilo lokukhusela igalelo.Imveliso evulekileyo yokusetha kwakhona i-drain, kunye nokucoca kunye nokulibaziseka, inika isibonakaliso esiyinyani sesimo senkqubo.Olu phawu luyayigatya imfuneko yecandelo elongezelelweyo lokongamela, ukonga iindleko kunye nesithuba sebhodi.Utshintsho olungenamthungo phakathi kweendlela ze-PWM kunye ne-PFM, kunye nokungathwali mthwalo ngoku okusebenzayo kwama-24 µA kuphela, kuqinisekisa ukusebenza kakuhle okuphezulu kunye nempendulo edlulayo eyongamileyo kuyo yonke imithwalo.
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
