Incazelo ye-TPS548B22
Idivayisi ye-TPS548B22 iyisiguquli sebuck esisodwa esihlangene esivumelana nesikhathi, isilawuli semodi ye-D-CAP3.Iklanyelwe ukunemba okuphezulu, ukusebenza kahle okuphezulu, ukusabela kwesikhashana okusheshayo, ukusebenziseka kalula, ukubala okuphansi kwezingxenye zangaphandle, kanye nezinhlelo zamandla aqaphela isikhala.
Le divayisi ihlanganisa umuzwa ophelele ohlukile, ama-FET ahlanganisiwe e-TI anokumelana okuphezulu kwe-sideon okungu-4.1 mΩ kanye nokumelana nohlangothi oluphansi okungu-1.9 mΩ.Idivayisi iphinde ibe nereferensi enembile engu-0.5%, i-0.9-V enebanga lokushisa eliphakathi kuka--40°C no-+125°C. Izici ezincintisanayo zihlanganisa: isibalo esiphansi kakhulu sengxenye yangaphandle, ukulawulwa okunembile komthwalo nokulawulwa komugqa, ukunemba kwephoyinti lokukhipha amandla kagesi, okuzenzakalelayo- yeqa noma ukusebenza kwemodi ye-FCCM, nokulawula kwangaphakathi kwe-soft-start.
Idivayisi ye-TPS548B22 itholakala ngephakheji engu-7 mm × 5 mm, 40-pin, LQFN-CLIP (RVF) (i-RoHs exempted).
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
