♠ LP8866S-Q1 Ukuboniswa kweMoto ye-LED-backlight Driver enemijelo emithandathu eyi-150-mA
I-LP8866S-Q1 yimoto yomqhubi we-LED ophezulu kunye nomlawuli wokunyusa.I-Six highprecision current sinks ixhasa ukutshintshwa kwesigaba esilungiswa ngokuzenzekelayo ngokusekelwe kwinani lamajelo asetyenziswayo.Ukukhanya kwe-LED kunokulawulwa kwihlabathi liphela ngojongano lwe-I²C okanye igalelo le-PWM.
Isilawuli se-boost sinolawulo lombane oluguquguqukayo olusekwe kwi-headroom voltages yee-sinki zangoku ze-LED.Eli nqaku linciphisa ukusetyenziswa kwamandla ngokulungelelanisa amandla ombane okunyusa ukuya kwelona nqanaba lisezantsi ngokwaneleyo kuzo zonke iimeko.Uluhlu olubanzi oluhlengahlengiswayo luvumela i-LP8866S-Q1 ukunqanda ukuphazamiseka kwibhendi yerediyo ye-AM.
I-LP8866S-Q1 ixhasa ukufiphala kwe-PWM eyakhelwe-ngaphakathi kunye ne-analog dimming yangoku, enciphisa i-EMI, yandisa ubomi be-LED, kwaye yandise ukusebenza kakuhle okupheleleyo.
