Sharaxaada LP8867-Q1
LP8867-Q1, LP8869-Q1 waa baabuur aad isku dhafan, EMI hooseeya, si sahlan loo isticmaali karo darawalka LED oo leh beddelka DC-DC.Beddeliyaha DC-DC wuxuu taageeraa xoojinta iyo hawlgalka qaabka SEPIC labadaba.Qalabku waxa uu leeyahay afar ama saddex saxan saxan oo saxan oo hadda jira kuwaas oo la isku dari karo si loo helo awoodda hadda jirta.
Beddeliyaha DC-DC wuxuu leeyahay kontoroolka korantada ee wax soo saarka ee la qabsiga ee ku saleysan koronta hore ee LED.Habkani waxa uu yareeyaa isticmaalka korantada iyada oo la hagaajinayo tamarta ilaa heerka ugu hooseeya ee ku filan dhammaan xaaladaha.Si loo dhimo EMI DC-DC waxay taageertaa fidinta spectrum ee beddelka soo noqnoqda iyo isku xidhka dibadda oo leh biin go'an.Soo noqnoqoshada la isku hagaajin karo ee ballaaran ayaa u oggolaanaysa LP886x-Q1 in ay iska ilaaliso qaska xargaha soo noqnoqda ee xasaasiga ah.
Kala duwanaanshaha korantada ee LP886x-Q1 waa laga bilaabo 4.5 V ilaa 40 V si loo taageero bilowga-joojinta baabuurta iyo xaalada qashinka.LP886x-Q1 wuxuu isku daraa astaamaha ogaanshaha cilladaha ballaaran.
