♠ TPS92692, TPS92692-Q1 Xakamaynta Saxnaanta Sare ee LED oo leh Habaynta Soo noqnoqoshada Spectrum.
TPS92692 iyo TPS92692-Q1 waa saxsanaan sare oo sax ah qaabka hadda ku saleysan kontaroolayaasha loogu talagalay inay taageeraan kor u kaca/hoosyada dusha sare ee darawalka LED. Qalabku wuxuu ku daraa cod-weyneeye hadda tareen-ilaa-tareen ah si loo cabbiro LED-ga hadda jira oo loo faafiyo farsamada habaynta soo noqnoqda ee waxqabadka EMI ee la hagaajiyay.
Waxqabadkan sare ee kontoroolka LED wuxuu si madax banaan u habeyn karaa LED-ga hadda jira isagoo isticmaalaya farsamooyinka yaraynta analoogga ama PWM. Jawaab celinta toosan ee analooga ah ee ka badan 15:1 ayaa lagu helaa iyadoo lagu kala duwanaanayo korantada guud ahaan gelinta analogga impedance high (IADJ). Dimmaynta PWM ee LED-ka hadda waxa lagu gaaraa iyada oo si toos ah wax looga beddelo pin-gelinta DIM/PWM ee wareegga shaqada ee la doonayo ama iyada oo la awoodsiiyo wareegga koronto-dhaliyaha PWM gudaha. Soo-saare PWM wuxuu u turjumayaa danabka DC ee DIM/PWM biinka wareegga shaqada ee u dhiganta isagoo isbarbar dhigaya koronto-dhaliye saddex-xagal ah. Soo saarida darawalka albaabka PDRV ee ikhtiyaarka ah waxaa loo isticmaali karaa in lagu wado MOSFET taxane P-Channel dibadda ah.
Qalabka TPS92692 iyo TPS92692-Q1 waxay taageeraan hubinta heerka LED ee joogtada ah iyada oo loo marayo soosaarka kormeeraha (IMON). Aaladaha waxa kale oo ka mid ah soo saarida tusaha cilada dheecaanka furan si ay u muujiso qulqulka LED-ka, kor u kaca wax soo saarka iyo xaaladaha wax soo saarka.
