Incazelo
Umndeni wamadivayisi we-TPS9260x-Q1 uyisiteshi esisodwa kanye ne-LED yamanje eneziteshi ezimbili eziphezulu
umshayeli.Ngokuvikeleka okugcwele nokuxilongwa, lo mndeni wamadivayisi unikezelwe futhi ufaneleka kahle ekukhanyisweni kwezimoto ngaphambili.Isisekelo somshayeli ngamunye ozimele siyisilawuli se-boost yemodi yamanje.Isilawuli ngasinye sinamaluphu empendulo amabili azimele, iluphu yempendulo yamanje enenzwa ye-highside current kanye ne-voltage-feedback loop enenethiwekhi yangaphandle yesihlukanisi.Isilawuli siletha i-voltage ephumayo engashintshi noma i-aconstant output current.Umthwalo oxhunyiwe unquma ukuthi idivayisi ilawula amandla aphumayo angashintshi (uma isekethe ifinyelela endaweni yokubeka yamanje ngaphambi kwephoyinti lokusetha i-voltage) noma i-voltage ephumayo engaguquki (uma isekethe ifinyelela endaweni yokubeka i-voltage ifinyelelwa kuqala, isibonelo, endaweni evulekile. -isimo sokulayisha).Isilawuli ngasinye sisekela zonke izinhlobo ze-topology ezivamile ezifana ne-asboost, boost-to-battery, SEPIC, noma i-flyback.Ukusetshenziswa komshayeli we-PMOS FET ohlangothini oluphezulu okokufiphalisa i-PWM yentambo ye-LED kanye nokunqamuka uma kuba mfushane ngaphandle. isekethe ukuya ku-GND ukuze kuvikelwe isekethe.Ulwazi Lwedivayisi(1)INGXENYE INOMBOLO YOMBONO-VOLTAGE
