e hlahisa li-drive tsa backlight tsa koloi tse nang le li-converter tse kopaneng tsa boost ho amohela maemo a mocheso o tlase haholo
2021-07-09
Gage Automotive-Phupu 6th, Maxim Integrated Product e qala mocha oa li-channel tse 'nè, khatello e tlase, koloi ea morao-rao ea LED ea likoloi MAX25512. ka converter e kenyellelitsoeng ea boost.Ena ke eona feela tharollo e kopaneng e bolokang khanya e felletseng le e sa feleng ea ponts'o ea koloi esita le maemong a qalang a batang haholo a tlase joalo ka 3V input voltage.
O khanna o kenyelletsa likanale tse 'ne tsa 120mA tse nang le ts'ebetso e phahameng ka ho fetisisa indastering ha li sebetsa ka maqhubu a 2.2MHz, ho fihla ho 91%. MAX25512 e phuthetsoe ka lithapo tse nyane tse 24, 4mm x 4mm x 0.75mm square flat no pin (QFN). Koloi e fokotsehile ka 30% ka lebaka la kopanyo e phahameng le likarolo tse ka ntle tse hlakotsoeng.
Tsamaiso ea kajeno ea ho qala le ho emisa koloi e ntlafatsa moruo oa mafura, empa hape e etsa hore ho be thata bakeng sa tsamaiso ea phetiso ea matla ho boloka khanya e tšoanang ea pontšo ha e tsosolosoa hape. Mohlala, qalong, lits'ebetso tse joalo ka mabone a bonts'itsoeng li ka angoa ke tikoloho e batang ea ho qala, 'me enjene e sebelisa matla a feteletseng a betri ea koloi e etsa hore skrine e tingoe le ho buloa hape. Maxim Integrated's MAX25512 LED backlit drive e na le matla a tlase a ts'ebetso joalo ka 3V, kamora ho qala ntle le ho eketsa converter ea pre-boost ho sireletsa leihlo hore le se ke la sitisoa ke matla.
"Baetsi ba likoloi ba hloka li-drive tsa LED tse nang le kopanyo e phahameng ho fokotsa litšenyehelo tsa tharollo le sebaka sa PCB," ho boletse Szu-Kang Hsien, mookameli oa tsamaiso ea khoebo Maxim Integrated. Maxim Integrated's MAX25512 LED drive e fana ka boemo bo phahameng ka ho fetisisa ba ho kopanya le ho sebetsa hantle ho 2.2MHz switching frequencies."
