Inkcazelo ye-TPS62147
I-TPS62147 kunye ne-TPS62148 zisebenza kakuhle kwaye kulula ukuzisebenzisa iziguquli ze-synchronous step-downDC/DC, ezisekwe kwi-DCS-Control™Topology.Uluhlu olubanzi lwamandla ombane we-3-V ukuya kwi-17-V lubenza bafaneleke kwiiseli ezininzi ze-Li-Ion kunye ne-12-V yokubonelela ngeentsimbi eziphakathi.Izixhobo zibonelela nge-2-A imveliso eqhubekayo yangoku.Bangena ngokuzenzekelayo kwiNdlela yokuGcina aMandla kumthwalo okhanyayo ukugcina ukusebenza kakuhle okuphezulu kulo lonke uluhlu lomthwalo.Ngaloo nto, zifaneleka kakuhle kwizicelo ezifuna ukusebenza okulindileyo okuqhagamshelweyo, njengePC yoshishino kunye novavanyo lwevidiyo.Nge-MODE pin isete phantsi, i-switchingfrequency ilungiswa ngokuzenzekelayo ngokusekelwe kwimveliso yangoku kunye nakwigalelo kunye ne-outputvoltage.Obu buchwephesha bubizwa ngokuba yi-Automatic Efficiency Enhancement (AEE™) kwaye igcina i-highconversion esebenzayo kulo lonke uluhlu lokusebenza.I-TPS62147, i-TPS62148 ibonelela ngokuchaneka kwe-1% ye-outputvoltage kwimodi ye-PWM kwaye ke yenza ukuba uyilo lombane ngokuchaneka okuphezulu kwe-outputvoltage.I-pin ye-FSEL ivumela ukuseta i-frequency yokutshintsha kwimo ye-PWM enyanzelweyo ye-1.25 MHz okanye i-2.5 MHz, ngokulandelanayo.
Umsinga othe cwaka oqhelekileyo yi-18 µA.Kwimowudi yokuvala indawo yangoku iba yi-1µA.
Izixhobo zifumaneka njengenguqu ehlengahlengiswayo, efakwe kwi-3-mm × 2-mm VQFNpackage.
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
