♠ LP8866S-Q1 Mokhanni oa Lebone la Likoloi la LED-backlight le likanale tse Tšeletseng tsa 150-mA
LP8866S-Q1 ke mokhanni oa LED oa koloi o sebetsang hantle haholo o nang le matla a taolo. Six highprecision current sinks e ts'ehetsa ho fetoha ha mekhahlelo e lokisoang ka bo eona ho latela palo ea likanale tse sebelisoang. Khanya ea LED e ka laoloa lefatšeng ka bophara ka sebopeho sa I²C kapa ho kenya PWM.
Mookameli oa boost o na le taolo ea motlakase e feto-fetohang e ipapisitseng le li-voltages tsa headroom tsa sinki tsa hajoale tsa LED. Karolo ena e fokotsa tšebeliso ea matla ka ho fetola matla a motlakase ho ea boemong bo tlaase ka ho fetisisa maemong 'ohle. Maqhubu a fapaneng a feto-fetohang a lumella LP8866S-Q1 ho qoba tšitiso bakeng sa sehlopha sa seea-le-moea sa AM.
LP8866S-Q1 e ts'ehetsa ho fifala ha hybrid PWM le dimming ea hona joale ea analog, e fokotsang EMI, e lelefatsa bophelo ba LED, 'me e eketsa ts'ebetso e felletseng ea optical.
