♠ TPS65251 4.5-V zuwa 18-V Input, High-A halin yanzu, Aiki tare Mataki-saukar Buck Mai Sauya Uku Tare da Haɗin FET
TPS65251 yana fasalta kewayon shigarwa mai faɗi guda uku masu aiki tare da manyan masu juyawa. An ƙera masu juyawa don sauƙaƙa aikace-aikacen sa yayin baiwa mai ƙira zaɓi don inganta amfanin su gwargwadon aikace-aikacen da aka yi niyya.
Masu canzawa za su iya aiki a cikin tsarin 5-, 9-, 12- ko 15-V kuma suna da haɗin wutar lantarki. Za'a iya saita ƙarfin wutar lantarki a waje ta amfani da mai rarraba resistor zuwa kowace ƙima tsakanin 0.8 V kuma kusa da wadatar shigarwa. Kowane nau'in mai canzawa yana ba da damar jinkirin farawa don dalilai na tsarawa, fil mai farawa mai laushi wanda ke ba da damar daidaita lokacin farawa mai laushi ta hanyar zabar capacitor mai farawa mai laushi, da madaidaicin iyaka na yanzu (RLIMx) wanda ke ba da damar mai ƙira don daidaita iyakar halin yanzu ta zaɓin resistor na waje da haɓaka zaɓin inductor. Ikon yanayin halin yanzu yana ba da izinin RC mai sauƙi.
Ana iya saita mitar masu canzawa tare da resistor na waje da aka haɗa da fil ɗin ROSC ko za'a iya aiki tare da agogon waje da aka haɗa da fil ɗin SYNC idan an buƙata. An ƙera masu kula da sauyawa don aiki daga 300 kHz zuwa 2.2 MHz. 180° daga aiki na lokaci tsakanin Buck 1 da Buck 2, 3 (Buck 2 and 3 run in time) yana rage buƙatun tace shigarwa.
