♠ TPS61193 Waxqabad Sare oo Saddex-Channel LED ah
TPS61193 waa hufnaan sare, EMI hooseeya, si sahlan loo isticmaali karo darawalka LED oo leh dabacsanaan si uu u taageero codsiyo kala duwan.Waxay leedahay saddex saxan oo saxan oo saxan oo hadda jira kuwaas oo la isku dari karo si loo helo awoodda hadda jirta.
TPS61193 waxay leedahay DC-DC isku dhafan oo taageeraya xoojinta iyo hawlgalka qaabka SEPIC.Beddeliyuhu waxa uu leeyahay kontoroolka korantada ee wax soo saarka ee la qabsiga ee ku salaysan laydhka qolalka madaxa ee hadda jira.Habkani waxa uu yareeyaa isticmaalka korantada iyada oo la hagaajinayo danab ilaa heerka ugu hooseeya ee ku filan dhammaan xaaladaha.Si loo xakameeyo EMI beddeliyaha DC-DC wuxuu kaalmeeyaa fidinta kala duwanaanshaha beddelka inta jeer iyo is-waafajinta dibadda oo leh biin go'an.
TPS61193 waxay leedahay kala duwanaansho galmo balaadhan oo kala duwan oo u dhaxaysa 4.5 V ilaa 40 V si loo helo taageero adag ee noocyada kala duwan ee codsiyada.TPS61193 waxay isku daraysaa astaamaha ogaanshaha cilladaha.Qalabku waxa uu taageeraa saamiga dhimista dhalaalka PWM ee 10 000:1 ee 100-Hz gelinta PWM.
