Incazelo ye-TPS54336A
Umndeni wamadivayisi we-TPS5433xA iziguquli ezivumelanisiwe ezinobubanzi be-input-voltage obungu-4.5 ukuya ku-28 V. Lezi zixhobo zihlanganisa i-FET ehlanganisiwe yohlangothi oluphansi eshintshayo eqeda isidingo se-diode yangaphandle enciphisa ukubalwa kwengxenye.
Ukusebenza kahle kukhuliswa ngama-MOSFET angu-128-mΩ kanye nama-84-mΩ ahlanganisiwe, i-IQ ephansi kanye nokweqa ukushaya kwenhliziyo emithwalweni elula.Ngokusebenzisa iphinikhodi yokunika amandla, amandla okunikezwayo okuvala shaqa ancishiswa abe ngu-2 μA.Lesi siguquli se-step-down (ibhakede) sinikeza ukulawulwa okunembile kwemithwalo ehlukahlukene enereferensi kagesi elawulwa kahle engu-1.5% ngaphezu kwezinga lokushisa.
Umkhawulo wamanje womjikelezo womjikelezo ku-MOSFET yohlangothi oluphezulu uvikela umndeni we-TPS5433xA wamadivayisi ezimeni ezigcwele kakhulu futhi uthuthukiswa umkhawulo wamanje wokuthola uhlangothi oluphansi ovimbela ukubaleka kwamanje.Umkhawulo wamanje ozikayo oseceleni eliphansi uvala i-MOSFET yohlangothi oluphansi ukuze kuvinjwe amandla amanje ahlehlayo amaningi.Ukuvikelwa kwe-Hiccup kuqalwa uma isimo se-overcurrent siqhubeka isikhathi eside kunesikhathi esimisiwe.Ukuvalwa kwe-thermal kukhubaza idivayisi uma izinga lokushisa le-die lidlula umkhawulo futhi kunika idivayisi amandla futhi ngemva kwesikhathi esakhelwe ngaphakathi se-thermal hiccup.
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
