Inkcazelo ye-TPS54140A

Isixhobo se-TPS54140A yi-42-V, i-1.5-A, i-step-down regulator kunye ne-MOSFET ehlangeneyo ephezulu.Ulawulo lwemowudi yangoku lubonelela ngembuyekezo elula yangaphandle kunye nokukhethwa kwecandelo eliguquguqukayo.Imowudi yokutsiba i-ripple-pulse ephantsi yehlisa ukungathwali, unikezelo olulawulwayo lwemveliso lwangoku ukuya kwi-116 µA.Usebenzisa iphini yokuvula, ukuvala unikezelo lwangoku kuncitshiswe ukuya kwi-1.3 µA.

I-Undervoltage lockout isetelwe ngaphakathi kwi-2.5 V, kodwa inokunyuswa ngokusebenzisa i-pin yokuvumela.Irempu yokuqalisa amandla ombane ephumayo ilawulwa sisikhonkwane sokuqala esicothayo esinokulungiselelwa ukulandelelana/ukulandelela.Umbane ovulekileyo wamandla ombane ubonisa ukuba imveliso iphakathi kwe-94% ukuya kwi-107% yombane wayo.

Uluhlu olubanzi lokutshintsha okuphindaphindiweyo luvumela ukusebenza kakuhle kunye nobukhulu becandelo langaphandle ukuba luphuculwe.Ukugoqa okuphindaphindiweyo ngasemva kunye nokuvalwa kwe-thermal kukhusela inxalenye ngexesha lemeko yokulayisha ngaphezulu.

Ngaphambili: I-TPS73133DBVR 150-mA, ukuchaneka okuphezulu

Okulandelayo: OPA4322AIPWR Quad, 5.5-V, 20-MHz

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
