Gage Automotive-Julayi 6th, Maxim Integrated Product imayambitsa njira inayi, yotsika, yoyendetsa galimoto ya LED backlight MAX25512. ndi Integrated boost converter.Iyi ndiyo njira yokhayo yophatikizira yomwe imasunga kuwala kokwanira komanso kosalekeza kwa galimoto yowonetsera ngakhale pazikhalidwe zozizira kwambiri zoyambira zotsika kwambiri monga 3V input voltage.
Amayendetsa amaphatikizanso njira zinayi za 120mA zomwe zimakhala zogwira mtima kwambiri pamsika zikamagwira ntchito pafupipafupi 2.2MHz, mpaka 91%. MAX25512 ili mmatumba ang'onoang'ono mapini 24, 4mm x 4mm x 0.75mm lalikulu lathyathyathya opanda pini (QFN). Kuyendetsa kunachepetsedwa ndi 30% chifukwa cha kuphatikizika kwakukulu ndi kuletsedwa kwa zigawo zakunja.
Masiku ano galimoto yoyambira ndi kuyimitsa imapangitsa kuti mafuta azikhala bwino, komanso zimapangitsa kuti zikhale zovuta kuti makina otumizira magetsi azikhala ndi kuwala kofananira akayambiranso. Mwachitsanzo, poyambitsa, ntchito monga kuyatsa zowonetsera zingakhudzidwe ndi malo ozizira, ndipo injini yomwe imagwiritsa ntchito mphamvu ya batri ya galimoto imapangitsa kuti chiwonetserocho chizimitse ndikutsegulanso. The Maxim Integrated's MAX25512 LED backlit drive ili ndi voteji yotsika ngati 3V, itangoyamba popanda kuwonjezera chosinthira chowonjezera kuti chiteteze chowunikira ku kusokonezeka kwamagetsi.
"Opanga ma automaker amafunikira ma drive a LED okhala ndi kuphatikiza kwakukulu kuti achepetse ndalama zothetsera mavuto komanso dera la PCB," atero a Szu-Kang Hsien, director of business management ku Maxim Integrated. The Maxim Integrated's MAX25512 LED drive imapereka mulingo wapamwamba kwambiri wophatikizira komanso wogwira ntchito pa 2.2MHz masinthidwe ma frequency."
