♠ TPS61193 Kev Ua Haujlwm Siab Peb-Channel LED Tsav Tsheb
TPS61193 yog ib qho kev ua haujlwm siab, qis-EMI, yooj yim-rau-siv LED tsav tsheb nrog yooj yim los txhawb ntau yam kev siv. Nws muaj peb qhov kev ua haujlwm siab tam sim no uas tuaj yeem ua ke kom muaj peev xwm ntau dua tam sim no.
TPS61193 muaj kev sib koom ua ke DC-DC txhawb nqa thiab SEPIC hom kev ua haujlwm. Lub converter muaj adaptive tso zis voltage tswj raws li LED tam sim no dab dej headroom voltages. Cov yam ntxwv no txo qis kev siv hluav taws xob los ntawm kev kho qhov hluav taws xob kom qis qis txaus hauv txhua qhov xwm txheej. Rau EMI tswj DC-DC converter txhawb kev sib kis spectrum rau kev hloov zaus thiab ib qho kev sib txuas sab nraud nrog tus pin siab.
Lub TPS61193 muaj qhov dav input voltage ntau ntawm 4.5 V rau 40 V rau kev txhawb nqa zoo ntawm ntau hom kev siv. TPS61193 suav nrog ntau yam kev ua txhaum cai. Cov cuab yeej txhawb nqa PWM brightness dimming piv ntawm 10 000: 1 rau 100-Hz input PWM zaus.
