yethula amadrayivu e-backlight emoto aneziguquli ezididiyelwe ze-boost ukuze zivumelane nezindawo zokushisa eziphansi kakhulu
2021-07-09
I-Gage Automotive-Julayi 6, i-Maxim Integrated Product yethula amashaneli amane, ingcindezi ephansi, idrayivu ye-LED backlight yezimoto engu-MAX25512. nge-integrated boost converter.Lesi ukuphela kwesixazululo esididiyelwe esigcina ukukhanya okuphelele nokungaguquki kwesibonisi semoto ngisho nasezimeni zokuqala ezibanda kakhulu eziphansi njenge-voltage engu-3V.
Ushayela uhlanganisa iziteshi ezine ze-120mA ezisebenza kahle kakhulu embonini uma esebenza kumafrikhwensi angu-2.2MHz, afika ku-91%. I-MAX25512 ihlanganiswe ngezikhonkwane ezincane ezingu-24, 4mm x 4mm x 0.75mm square flat no pin (QFN). Idrayivu yehliswe ngo-30% ngenxa yokuhlanganiswa okuphezulu kanye nezingxenye zangaphandle ezikhanseliwe.
Uhlelo lwanamuhla lokuqalisa nokuma kwezimoto luthuthukisa ukonga kukaphethiloli, kodwa futhi lwenza kube nzima ukuthi uhlelo lokudluliswa kwamandla kagesi lugcine ukukhanya okufanayo kwesibonisi uma yethulwa kabusha. Isibonelo, ekuqaleni, imisebenzi efana nokukhanyisa ingase ithintwe indawo ebandayo yokuqala, futhi injini esebenzisa amandla ebhethri emoto amaningi ibangela ukuthi isibonisi sicime futhi sivuleke kabusha. Idrayivu ye-backlit ye-Maxim Integrated ye-MAX25512 LED ine-voltage ephansi yokusebenza njenge-3V, ngemuva kokuqaliswa ngaphandle kokwengeza isiguquli se-pre-boost ukuvikela imonitha ekuphazamisekeni kwamandla.
"Abakhiqizi bezimoto badinga amadrayivu e-LED anokuhlanganiswa okuphezulu ukuze banciphise izindleko zesixazululo nendawo ye-PCB," kusho uSzu-Kang Hsien, umqondisi wokuphathwa kwebhizinisi kwaMaxim Integrated. Idrayivu ye-LED ye-Maxim Integrated's MAX25512 inikeza izinga eliphezulu kakhulu lokuhlanganisa nokusebenza kahle kumafrikhwensi wokushintshwa angu-2.2MHz."
