Inkcazelo ye-TPS92513HV
I-TPS92513/HV yi-1.5A i-step-down (i-buck) abalawuli bangoku kunye ne-MOSFET edibeneyo yokuqhuba ii-LED zangoku eziphezulu.Ifumaneka nge-42 V kunye ne-60 V (HV) yokufaka uluhlu, aba baqhubi be-LED basebenza kumsebenzisi okhethiweyo we-fixed-frequency kunye ne-peak-current mode control kunye nokuhambisa umgca obalaseleyo kunye nokulawulwa komthwalo.
Abaqhubi be-LED be-TPS92513/HV be-LED bafaka amagalelo ahlukeneyo e-analog kunye ne-pulse wide modulation (PWM) dimming kungabikho kuthomalalisa ulawulo lokuqaqamba okufezekisa umlinganiselo wokuthelekisa omkhulu kuno-10:1 nangaphezulu kune-100:1, ngokulandelelanayo.Igalelo le-PWM lihambelana nemigangatho yengqiqo ye-voltage ephantsi ukwenzela ujongano olulula kuluhlu olubanzi lwe-microcontrollers.I-analog ye-LED yangoku i-setpoint ilungiswa ukusuka kwi-0 V ukuya kwi-300 mV usebenzisa i-IADJ igalelo kunye ne-0 V yangaphandle ukuya kwi-1.8 V isignali.
Ukusetyenziswa kwemitya emininzi kusetyenziswa abaqhubi be-LED be-TPS92513/HV ezimbini okanye ngaphezulu, i-oscillator yangaphakathi inokuqhutywa ngaphezulu yiwotshi yangaphandle eqinisekisa ukuba zonke iziguquli zisebenza ngamaxesha aqhelekileyo ngaloo ndlela zinciphisa amandla okubetha kunye nokwenza lula inkqubo yokucoca i-EMI.Igalelo elihlengahlengiswayo phantsi kwe-voltage lockout (UVLO) kunye ne-hysteresis inika uguquko ekusekweni kombane wokuqalisa/wokumisa ngokusekelwe kwiimeko zombane wobonelelo.
I-TPS92513 ibandakanya ukhuseleko oludlulayo lomjikelo ngomjikelo kunye nokhuseleko lokuvalwa kwe-thermal.Iyafumaneka nge-10-pin ye-HVSSOP PowerPAD™ package.
