♠ TPS92692, TPS92692-Q1 Ukuchaneka okuPhakamileyo kwesiLawuli se-LED esine-Sreader Spectrum Frequency Modulation
I-TPS92692 kunye ne-TPS92692-Q1 ziphezulu zokuchaneka kwemowudi yangoku esekelwe kubalawuli abayilelwe ukuxhasa i-top-up / down LED driver topology. Isixhobo sibandakanya i-amplifier yangoku kaloliwe ukuya kuloliwe ukulinganisa i-LED yangoku kunye ne-spectrum frequency modulation technique ukuze kuphuculwe ukusebenza kwe-EMI.
Esi silawuli siphezulu se-LED sinokumodareyitha ngokuzimeleyo i-LED yangoku usebenzisa i-analog okanye i-PWM dimming techniques. Umgca we-analog dimming impendulo engaphezulu kwe-15: uluhlu lwe-1 lufunyenwe ngokutshintsha i-voltage kuyo yonke i-impedance analog adjustment (IADJ) igalelo. I-PWM dimming ye-LED yangoku iphunyezwa ngokumodareyitha ngokuthe ngqo i-DIM/PWM i-pin yokufaka kunye nomjikelo ofunekayo womsebenzi okanye ngokuvumela isekethe ye-PWM yejeneretha yangaphakathi. Ijeneretha ye-PWM iguqulela i-voltage ye-DC kwi-DIM/PWM pin ukuya kumjikelezo womsebenzi ohambelanayo ngokuyithelekisa nejenereyitha yamaza enxantathu yangaphakathi. Imveliso yomqhubi wesango le-PDRV ekhethiweyo ingasetyenziselwa ukuqhuba uthotho lwe-P-Channel MOSFET.
Izixhobo ze-TPS92692 kunye ne-TPS92692-Q1 zixhasa ukukhangela ubume be-LED ngokuqhubekayo nge-monitor yangoku (IMON) imveliso. Izixhobo zikwabandakanya ukukhutshwa kwesalathisi esivulekileyo sombhobho ukubonisa i-LED overcurrent, i-output overvoltage kunye neemeko zokungabikho kombane.
