Incazelo ye-LMR23625
I-LMR23625 SIMPLE SWITCHER iyisilawuli esisebenziseka kalula esingu-36-V, 2.5-A esivumelanayo sokuya phansi.Ngobubanzi bokufakwayo okubanzi kusuka ku-4 V kuya ku-36 V, idivayisi ifanele ukusetshenziswa kwezimboni ezihlukahlukene zokulungiswa kwamandla kusuka emithonjeni engalawulwa.Ukulawulwa kwemodi yamanje ephezulu kusetshenziselwa ukuzuza isinxephezelo esilula sokulawula iluphu kanye nomkhawulo wamanje womjikelezo nomjikelezo.I-current ethule engu-75 µA iyenza ifanelekele amasistimu asebenza ngebhethri.Ukuvala shaqa okungu-2 µA okuphansi kakhulu kungandisa impilo yebhethri.Isinxephezelo se-loop yangaphakathi sisho ukuthi umsebenzisi ukhululekile emsebenzini oyisicefe wokuklama isinxephezelo seluphu.Lokhu futhi kunciphisa izingxenye zangaphandle.
Idivayisi inenketho yemodi ye-FPWM ye-fixed-frequency ukuzuza i-ripple encane yokuphuma-voltage ekulayishweni okukhanyayo.Umndeni onwetshiwe we-HSOIC uyatholakala kokuthi 1-A (LMR23610) kanye ne-3-A (LMR23630) ilayishe izinketho zamanje kumaphakheji ahambisanayo wokuphin-to-pin avumela isakhiwo se-PCB esilula, nesilungile.Ukunemba kokunika amandla okokufaka kuvumela ukwenziwa lula kokulawula isilawuli nokulandelana kwamandla esistimu.Izici zokuvikela zifaka umkhawulo wamanje womjikelezo womjikelezo, ukuvikela i-hiccup-circuit short-circuit kanye nokuvalwa kokushisa ngenxa yokushabalaliswa kwamandla amaningi.
1. Obani abasebenzi bomnyango wakho we-R & D?Yiziphi iziqu zakho?
-R & D Umqondisi: yenza uhlelo lwesikhathi eside lwe-R & D lwenkampani futhi babambe isiqondiso socwaningo nentuthuko;Qondisa futhi uqondise umnyango we-r&d ukuze usebenzise isu le-r&d lenkampani kanye nohlelo lonyaka lwe-R&D;Lawula inqubekelaphambili yokuthuthukiswa komkhiqizo futhi ulungise uhlelo;Misa ithimba locwaningo lomkhiqizo elihle kakhulu nelokuthuthukisa, abacwaningi mabhuku kanye nokuqeqeshwa okuhlobene nabasebenzi bezobuchwepheshe.
Umphathi we-R & D: yenza uhlelo olusha lwe-R & D futhi ubonise ukuthi kungenzeka uhlelo;Ukugada nokuphatha inqubekelaphambili kanye nekhwalithi yomsebenzi we-r&d;Cwaninga ukuthuthukiswa komkhiqizo omusha futhi uphakamise izixazululo ezisebenzayo ngokuvumelana nezidingo zamakhasimende emikhakheni ehlukene
Abasebenzi be-R&d: baqoqa futhi balungise idatha ebalulekile;Uhlelo lwekhompyutha;Ukwenza izivivinyo, izivivinyo kanye nokuhlaziya;Lungiselela izinto zokwakha kanye nezinto zokusebenza zokuhlola, izivivinyo nokuhlaziya;Rekhoda idatha yokulinganisa, yenza izibalo futhi ulungiselele amashadi;Yenza izinhlolovo zezibalo
2. Uthini umbono wakho wocwaningo nokuthuthukiswa komkhiqizo?
- Ukwakhiwa komkhiqizo kanye nomqondo wokukhethwa komkhiqizo kanye nokuhlolwa kwencazelo yomkhiqizo kanye nomklamo wepulani yephrojekthi kanye nokuthuthukiswa kokuhlolwa komkhiqizo kanye nokwethulwa kokuqinisekisa emakethe
