♠ TPS61193 High-Performance Three-Channel LED Dalaivala
TPS61193 ndi yokwera kwambiri, yotsika EMI, yosavuta kugwiritsa ntchito dalaivala wa LED ndi kusinthasintha kuthandizira ntchito zosiyanasiyana. Ili ndi masinki atatu olondola kwambiri apano omwe amatha kuphatikizidwa kuti azitha kuchita bwino kwambiri.
TPS61193 ili ndi DC-DC yophatikizika yomwe imathandizira kulimbikitsa ndi SEPIC mode ntchito. Chosinthiracho chimakhala ndi mphamvu yosinthira mphamvu yamagetsi yotengera ma voliyumu amakono a sink headroom a LED. Izi zimachepetsa kugwiritsa ntchito mphamvu mwa kusintha mphamvu yamagetsi kuti ikhale yotsika kwambiri muzochitika zonse. Pakuti EMI kulamulira DC-DC Converter amathandiza sipekitiramu kufalikira kwa kusintha pafupipafupi ndi kalunzanitsidwe kunja ndi pini odzipereka.
TPS61193 ili ndi mphamvu zambiri zolowera kuchokera ku 4.5 V mpaka 40 V kuti zithandizire mitundu yosiyanasiyana ya mapulogalamu. TPS61193 imaphatikiza zinthu zambiri zowunikira zolakwika. Chipangizochi chimathandizira PWM kuwala kwa dimming ratio ya 10 000:1 kwa 100-Hz kulowetsa PWM pafupipafupi.
