Incazelo ye-TPS53219A
Idivayisi ye-TPS53219A iyisilawuli sebhaka elilodwa esinosayizi omncane esinokulawula kwemodi ye-D-CAPmode eguquguqukayo.Idivayisi ifanele i-voltage ephumayo ephansi, yamanje ephezulu, isitimela samandla wesistimu ye-PC kanye nezinto ezifanayo zokusebenzisa indawo yokulayisha (POL) emikhiqizweni yabathengi bedijithali.Iphakheji elincane kanye nokubalwa kwamaphinikhodi okuncane konga isikhala ku-PCB, kuyilapho iphinikhodi ye-EN enikelwe kanye nokukhethwa kwamafrikhwensi okusethwe kusengaphambili kwenza idizayini yokuphakela amandla ibe lula.Imodi yokweqa ezimeni zomthwalo omncane, abashayeli bamasango aqinile, ne-FET R yohlangothi oluphansiI-DS(ivuliwe)inzwa yamanje isekela ukulahlekelwa okuphansi nokusebenza kahle kakhulu, phezu kwebanga elibanzi lomthwalo.I-voltage yokushintshashintsha (i-high-side FET drain voltage) ububanzi iphakathi kuka-4.5 V no-25 V, futhi ububanzi bamandla kagesi aphumayo buphakathi kuka-0.6 V no-5.5 V. I-TheTPS53219A itholakala ngamaphini angu-16, iphakheji ye-QFN ecaciswe kusukela ku- -40° C kuya ku +85°C.
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
