Inkcazelo ye-LMR23625
I-LMR23625 SIMPLE SWITCHER yi-36-V ekulula ukuyisebenzisa, i-2.5-A i-synchronous step-down regulator.Ngoluhlu olubanzi lwegalelo ukusuka kwi-4 V ukuya kwi-36 V, isixhobo sifanelekile kwizicelo ezahlukeneyo zemizi-mveliso yokulungiswa kwamandla ukusuka kwimithombo engalawulwayo.Incopho yolawulo lwemowudi yangoku isetyenziselwe ukuphumeza imbuyekezo elula yolawulo-loop kunye nomjikelo-ngomjikelo wangoku umda.Umsinga ozolileyo wama-75 µA uwenza ukuba alungele iinkqubo ezisebenza ngebhetri.I-ultra-low 2 µA ukuvalwa kombane kunokwandisa ubomi bebhetri.Imbuyekezo yelophu yangaphakathi ithetha ukuba umsebenzisi ukhululekile kumsebenzi odinayo woyilo lwembuyekezo yelophu.Oku kwakhona kunciphisa amacandelo angaphandle.
Isixhobo sinokhetho lwe-fixed-frequency mode ye-FPWM ukufikelela kwimveliso encinci-i-voltage ripple kumthwalo okhanyayo.Usapho olwandisiweyo lwe-HSOIC lufumaneka kwi-1-A (LMR23610) kunye ne-3-A (LMR23630) yokulayisha iinketho zangoku kwiipakethe ezihambelanayo ze-pin-to-pin evumela i-PCB elula, eyona nto ilungileyo.Ukuchaneka kwenza igalelo livumela ukwenziwa lula kolawulo lomlawuli kunye nolandelelwano lwamandla enkqubo.Iimpawu zokukhusela zibandakanya umda wangoku we-cycle-by-cycle, i-hiccup-mode yokukhusela i-short-circuit kunye nokuvalwa kwe-thermal ngenxa yokutshatyalaliswa kwamandla amaninzi.
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
