yazisa iidrive zokukhanya kwemoto kunye neziguquli ezidityanisiweyo zokunyusa ukwamkela indawo yobushushu obuphantsi kakhulu
2021-07-09
I-Gage Automotive-Julayi 6th, i-Maxim Integrated Product isungula i-channel ezine, uxinzelelo oluphantsi, i-automotive LED backlight drive MAX25512. kunye ne-integrated boost converter.Le kuphela kwesisombululo esidibeneyo esigcina ukukhanya okupheleleyo kunye nokuqhubekayo kwesiboniso sesithuthi nakwiimeko zokuqala ezibandayo eziphantsi njenge-3V igalelo lombane.
Uqhuba uquka iziteshi ezine ze-120mA ezinobona buchule buphezulu kwishishini xa zisebenza kwii-frequencies ze-2.2MHz, ukuya kuma-91%. I-MAX25512 ifakwe kwiikhonkwane ezincinci ze-24, 4mm x 4mm x 0.75mm square flat akukho pin (QFN). Ukuqhuba kwancitshiswa nge-30% ngenxa yokuhlanganiswa okuphezulu kunye nokucinywa kwamacandelo angaphandle.
Inkqubo yanamhlanje yokuqalisa kunye nokumisa imoto iphucula uqoqosho lwamafutha, kodwa yenza kube nzima ukuba inkqubo yokuhambisa amandla igcine ukukhanya okufanayo xa iphinda iqalwa. Umzekelo, xa uqalwa, imisebenzi efana nokukhanyisa isenokuchatshazelwa bume bendawo yokuqala ebandayo, kwaye injini isebenzisa amandla agqithisileyo ebhetri yemoto ibangela ukuba isibonisi sicime kwaye siphinde sivuleke. I-Maxim Integrated ye-MAX25512 ye-backlit drive ye-LED ine-voltage ephantsi yokusebenza njenge-3V, emva kokuqalisa ngaphandle kokongeza i-converter yangaphambili ukukhusela i-monitor ekuphazamisekeni kwamandla.
"Abenzi be-automakers badinga ii-LED drives kunye nokudibanisa okuphezulu ukunciphisa iindleko zesisombululo kunye nommandla we-PCB," kusho uSzu-Kang Hsien, umlawuli wolawulo lweshishini kwi-Maxim Integrated. I-Maxim Integrated's MAX25512 LED drive ibonelela ngelona nqanaba liphezulu lokudibanisa kunye nokusebenza kakuhle kwi-2.2MHz yokutshintsha amaza.
