♠ TPS65251 4.5-V kugeza 18-V Iyinjiza, Ihanze-Ibiriho, Ihuza Intambwe-Hasi Amashanyarazi atatu hamwe na FET ihuriweho
TPS65251 igaragaramo uburyo butatu bwagutse bwinjiza intera ikora neza buck ihindura. Abahindura bagenewe koroshya porogaramu yayo mugihe baha uwashizeho uburyo bwo guhitamo imikoreshereze yabo ukurikije intego igenewe.
Abahindura barashobora gukora muri sisitemu 5-, 9-, 12- cyangwa 15-V kandi bafite imbaraga za tristoriste. Ibisohoka voltage irashobora gushyirwaho hanze ukoresheje rezistor igabanya agaciro kamwe kari hagati ya 0.8 V kandi hafi yinjiza. Buri kintu gihindura kiranga pin yemerera gutangira gutinda kubikorwa bikurikiranye, yoroshye-itangira pin yemerera guhinduka byoroshye-gutangira igihe uhitamo capacitor-yoroshye yo gutangira, hamwe nimbibi igezweho (RLIMx) ifasha uwashushanyije guhindura imipaka igezweho muguhitamo rezistor yo hanze no guhitamo guhitamo inductor. Uburyo bugezweho bugenzura indishyi yoroshye ya RC.
Guhindura inshuro zimpinduka zirashobora gushyirwaho hamwe na rezistor yo hanze ihujwe na pin ya ROSC cyangwa irashobora guhuzwa nisaha yo hanze ihujwe na SYNC pin niba bikenewe. Igenzura rihindura ryakozwe kuva 300 kHz kugeza kuri 2.2 MHz. 180 ° hanze yicyiciro hagati ya Buck 1 na Buck 2, 3 (Buck 2 na 3 ikora mugice) igabanya ibyinjira byungururwa.
