♠ 40VIN, 75VOUT LED kontaroolayaasha
LT®3755, LT3755-1 iyo LT3755-2 waa kontaroolayaasha DC/DC loogu talagalay inay u shaqeeyaan sidii ilo joogto ah oo loogu talagalay wadista LED-yada hadda sarreeya.Waxay MOSFET ka kaxeeyaan awood N-channel dibadeed ah oo hooseeysa sahayda gudaha ee 7.15V.Inta jeer ee go'an, qaab dhismeedka qaabka hadda jira wuxuu keenaa hawlgal xasiloon oo ka badan noocyada kala duwan ee saadka iyo wax soo saarka.Firfircoonida dhulka lagu tixraacay ee FB pin waxay u adeegtaa sidii gelinta dhowr astaamood oo ilaalin LED ah,iyo sidoo kale waxay suurtogal ka dhigtaa beddelaha inuu u shaqeeyo sidii ilo-voltage joogto ah.Isku-hagaajinta inta jeer ee biinku waxay u oggolaanaysaa isticmaaluhu inuu barnaamijka ka dhigo inta jeer ee 100kHz ilaa 1MHz si loo wanaajiyo waxtarka, waxqabadka ama cabbirka qaybaha dibadda.
LT3755/LT3755-1/LT3755-2 dareenka wax soo saarka hadda ee dhinaca sare ee xadhigga LED.Dareenka dhinaca sare ee hadda jira waa nidaamka ugu dabacsan ee wadista LED-yada, u oggolaanaya kor u qaadista, qaabka buck ama qaabaynta qaabka kor u qaadista.Gelitaanka PWM wuxuu bixiyaa saami-dhimista LED-ka illaa 3000: 1, gelinta CTRL waxay bixisaa awood dheeraad ah oo yaraynta analoogga.
