Incazelo ye-TPS630250
Ama-TPS63025x asebenza kahle kakhulu, iziguquli ze-buck-boost zamanje ezithule zilungele ukusetshenziswa lapho i-voltage yokufaka iphezulu noma iphansi kunokukhiphayo.Okuphumayo kungahamba kufike ku-2 A kumodi ye-boost futhi kufike ku-4 A kumodi yebhali.Isilinganiso esiphezulu samanje kumaswishi sikhawulelwe kunani elijwayelekile elingu-4 A. I-TPS63025x ilawula amandla kagesi okukhiphayo phezu kwebanga eliphelele le-voltage yokufaka ngokushintsha ngokuzenzekelayo phakathi kwemodi yebhali noma ye-boost kuye ngokuthi i-voltage yokufaka iqinisekisa ukushintshwa okungenamthungo phakathi kwamamodi.Isiguquli se-buck-boost sisekelwe kusilawuli esingaguquki sefrikhwensi, i-pulse-width-modulation (PWM) sisebenzisa ukulungiswa okuvumelanayo ukuze kutholwe ukusebenza kahle okuphezulu kakhulu.Kumaza okulayisha aphansi, isiguquli singena Kumodi Yokonga Amandla ukuze sigcine ukusebenza kahle okuphezulu ebangeni lamanje lomthwalo ophelele.Kukhona iphinikhodi ye-PFM/PWM evumela umsebenzisi ukuthi akhethe phakathi kokusebenza kwemodi ye-PFM/PWM okuzenzakalelayo nokusebenza kwe-PWM okuphoqelelwe.Ngesikhathi semodi ye-PWM kusetshenziswa ifrikhwensi engaguquki engu-2.5 MHz.I-voltage ephumayo iyahleleka kusetshenziswa isihlukanisi sangaphandle esiphikisayo, noma sigxilwe ngaphakathi ku-chip.Isiguquli singacishwa ukuze kuncishiswe ukuphuma kwebhethri.Ngesikhathi sokuvala, umthwalo uyanqanyulwa ebhethrini.Idivayisi ipakishwe kuphakheji ye-WCSP yamaphini angu-20 enesilinganiso esingu-1.766 mm × 2.086mm kanye nephakheji le-HotRod lamaphini angu-14 elikala u-2.5 mm × 3mm.
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?
