♠ TPS61193 High-Performance Three-Channel LED Driver
I-TPS61193 i-high-efficiency, i-EMI ephantsi, ilula ukuyisebenzisa umqhubi we-LED onokuguquguquka ukuxhasa uluhlu olubanzi lwezicelo. Ineesinki ezintathu ezichanekileyo zangoku ezinokudityaniswa kwisakhono esiphezulu sangoku.
I-TPS61193 ine-DC-DC edibeneyo exhasa zombini ukunyusa kunye nokusebenza kwemowudi ye-SEPIC. Isiguquli sinolawulo lombane oluguquguqukayo olusekwe kwi-LED yangoku ye-sink headroom voltages. Olu phawu lunciphisa ukusetyenziswa kwamandla ngokulungelelanisa umbane ukuya kwinqanaba elisezantsi ngokwaneleyo kuzo zonke iimeko. Kulawulo lwe-EMI i-DC-DC converter ixhasa ukusasazeka kwe-spectrum yokutshintsha rhoqo kunye nongqamaniso lwangaphandle kunye nephini elizinikeleyo.
I-TPS61193 inoluhlu olubanzi lwamandla ombane ukusuka kwi-4.5 V ukuya kwi-40 V yenkxaso eyomeleleyo yeentlobo ezahlukeneyo zezicelo. I-TPS61193 idibanisa iimpawu ezibanzi zokubona iimpazamo. Isixhobo sixhasa i-PWM yokukhanya kwe-dimming ratio ye-10 000:1 ye-100-Hz igalelo le-PWM frequency.
