Sharaxaada TPS92513HV
TPS92513/HV waa 1.5A hoos u dhac (buck) nidaamiyayaal hadda leh MOSFET isku dhafan si loo kaxeeyo LED-yada hadda jira.Waxaa lagu heli karaa 42 V iyo 60 V (HV), darawalladan LED waxay ku shaqeeyaan isticmaale la xushay soo noqnoqoshada go'an oo leh koontaroolka ugu sarreeya ee hadda jira waxayna bixiyaan xariiq heer sare ah iyo nidaaminta culeyska.
Darawalada TPS92513/HV LED waxay muujinayaan agabyo kala duwan oo loogu talagalay isbarbardhigga is-beddelka analogga iyo garaaca garaaca wadnaha (PWM) iyada oo aan wax tanaasul ah la sameyn kontoroolka dhalaalka ee lagu gaaro saamiga isbarbardhigga ee ka weyn 10:1 iyo ka weyn 100:1, siday u kala horreeyaan.Soo gelinta PWM waxay la jaan qaadaysaa jaangooyooyinka macquulka ah ee korantada hoose ee loogu talagalay is-dhexgalka fudud ee baaxadda ballaaran ee microcontrollers.Meesha hadda jirta ee analooga ah ayaa lagu hagaajin karaa 0 V ilaa 300 mV iyadoo la adeegsanayo galinta IADJ oo leh calaamad 0 V ilaa 1.8 V dibadeed.
Codsiyada xargaha badan ee isticmaalaya laba ama in ka badan TPS92513/HV darawallada LED, oscillator-ka gudaha waxa lagu dhaafi karaa saacad dibadda ah oo hubinaysa in dhammaan beddelayaashu ay ku shaqeeyaan soo noqnoqoshada caadiga ah taas oo yaraynaysa suurtagalnimada garaacista garaaca iyo fududaynta nidaamka EMI.Wax gelinta la hagaajin karo ee quful ka hooseeya-voltage (UVLO) oo leh hysteresis ayaa bixisa dabacsanaan dejinta bilowga/joojinta danab ku salaysan xaaladaha tamarta sahayda.
TPS92513 waxa ku jira ilaalinta wareega-wareeg-wareegga ah iyo ilaalinta xidhitaanka kulaylka.Waxaa lagu heli karaa xirmo 10-pin ah oo HVSSOP PowerPAD™ ah.
