♠ TPS61196-Q1 6-String 400-mA WLED Driver yokhala ndi Dimming Yodziyimira payokha ya PWM Pa Chingwe Iliyonse
TPS61196-Q1 imapereka yankho lophatikizika kwambiri pakuwunikira kumbuyo kwa LCD yamagalimoto ndi ntchito yodziyimira payokha ya PWM yachingwe chilichonse. Chipangizochi ndi chowongolera pakali pano choyendetsa mpaka zingwe zisanu ndi chimodzi za WLED zokhala ndi ma LED angapo motsatizana. Chingwe chilichonse chili ndi chowongolera pakali pano chomwe chimapereka chosinthira cha LED kuchokera pa 50 mA mpaka 400 mA mkati mwa ± 1.5% kulondola kofananira. Magetsi ochepa pa sinki yapano amatha kukonzedwa mumtundu wa 0.3 V mpaka 1 V kuti agwirizane ndi zosintha zaposachedwa za LED. Mphamvu yolowera pa chipangizocho imachokera ku 8 V mpaka 30 V.
TPS61196-Q1 imasintha mphamvu yamagetsi yamagetsi owongolera kuti ingopereka magetsi ofunikira ndi chingwe cha LED chokhala ndi kutsika kwakukulu kwamagetsi akutsogolo kuphatikiza voteji yocheperako yofunikira pa pini ya IFB ya chingwecho, potero kumapangitsa kuti madalaivala azigwira bwino ntchito. Kusintha kwake pafupipafupi kumakonzedwa ndi chopinga chakunja kuchokera ku 100 kHz mpaka 800 kHz.
TPS61196-Q1 imathandizira kuwala kwa PWM mwachindunji. Chingwe chilichonse chimakhala ndi chowongolera chodziyimira pawokha cha PWM. Panthawi ya kuwala kwa PWM, magetsi a LED amayatsidwa kapena kuzimitsidwa pafupipafupi ndi ntchito zomwe zimatsimikiziridwa ndi chizindikiro chakunja cha PWM. Ma frequency a PWM amachokera ku 90 Hz mpaka 22 kHz.
TPS61196-Q1 imaphatikiza chitetezo chochulukirapo, chitetezo chafupipafupi, chitetezo cha ISET chachifupi mpaka pansi, chitetezo chotseguka ndi chachifupi cha diode, chitetezo chotseguka komanso chachifupi cha LED, komanso kutsekeka kwanyengo yotentha. Kuphatikiza apo, TPS61196-Q1 imatha kuzindikira pini ya IFB yayifupi mpaka pansi kuti iteteze chingwe cha LED. Chipangizochi chimaperekanso njira yotsekera yotsekera yotsekera komanso chitetezo chowonjezera chamagetsi.
