Umqhubi weSango loThutho lokuqhawula
Ukhuseleko olufutshane lweHiccup
Ngaphezulu koKhuseleko lombane
Ukusebenza okuzenzekelayo kwePFM-TPS61178
Indlela yePWM enyanzelweyo - TPS611781
3.0-mm x 3.5-mm 13-pin ye-VQFN Hotrod Package
Yenza uYilo oluSiko usebenzisa i-TPS61178 kunye neWEBHENCH®uMyili waMandla
Inkcazelo ye-TPS61178
Intsapho ye-TPS61178x yi-20-V ye-synchronous Boost converter kunye nomqhubi wesango owakhelwe ngaphakathi komthwalo wokuqhawula.I-TPS61178x idibanisa iiFET ezimbini zamandla aphantsi okuxhathisa: I-16-mΩ switchingFET kunye ne-16-mΩ rectifier FET.
I-TPS61178x isebenzisa ulawulo lwemowudi ye-frequency esisigxina kunye ne-slopecompensation edibeneyo.Kumthwalo olula, i-TPS61178 ingena kwimowudi ye-PFM ye-auto ngelixa i-TPS611781 ikwimo ye-PWM enyanzelekileyo.
I-TPS61178x inokwahlula imveliso kwicala lokufaka xa uvala.Nje ukuba imveliso ifinyeziwe, ingena kwimowudi ye-hiccup ukuthoba uxinzelelo lwe-thermal kwaye inokubuyisela ngokuzenzekelayo emva kokukhutshwa okufutshane.Ukongeza, i-TPS61178x nayo ine-OVP kunye nokhuseleko lobushushu ukunqanda ukusebenza kwempazamo.I-TPS61178x ikwi-3.0-mm x 3.5-mm 13-pin ye-VQFN iphakheji ene-dissipation ephuculweyo yokushisa.
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
