♠ TPS92638-Q1 8-Channel Linear LED Driver Ndi PWM Dimming
TPS92638-Q1 ndi dalaivala wa LED wokhala ndi njira zisanu ndi zitatu yokhala ndi dimming control ya PWM. Mapangidwe ake ndi abwino kuyendetsa zingwe zingapo za ma LED mpaka sing'anga
osiyanasiyana mphamvu.
Chipangizochi chimatha kuyendetsa zingwe zisanu ndi zitatu zokhala ndi ma LED amodzi kapena atatu mu chingwe chilichonse, pakali pano mpaka 70 mA panjira. Zotulutsa zimatha kufanana kuti zipereke magalimoto apamwamba kwambiri mpaka 560 mA.
Muzogwiritsa ntchito zingwe zingapo, chipangizochi chimapereka mwayi wokhala ndi kulumikizana kofanana kwa ma cathode a mbola za LED. Chifukwa chake, pali waya umodzi wokha wobwerera womwe ukufunika m'malo mwa chingwe chimodzi pa chingwe cha LED chomwe dongosolo lomwe lili ndi mphamvu zocheperako lingafune.
Chipangizochi chimakhala ndi mphamvu yosinthira magetsi a LED pakati pamakono apamwamba ndi otsika kuti ayime ndi mchira. Zotsutsa ziwiri zowunikira zimayika milingo iwiri yaposachedwa ya LED kuchokera pazotulutsa zilizonse.
Kuwunika kwa kutentha komwe kumaphatikizidwa kumachepetsa kuyendetsa kwa LED komweko ngati kutentha kwa IC junction kupitilira malire otentha. Kutentha kwapakati kumakonzedweratu kupyolera mu resistor kunja. Wina akhoza kuletsa mawonekedwe a kutentha kwapano polumikiza pini ya TEMP pansi. Kutulutsa kwa kutentha kwapakati monga magetsi a analogi kumapezeka ngati njira ya fakitale.
