TPS65251 igaragaramo ubugari butatu
kwinjiza intera ikora neza buck ihindura.Uwiteka
abahindura bagenewe koroshya ikoreshwa ryayo
mugihe uha uwashizeho uburyo bwo guhitamo ibyabo

Abahindura barashobora gukora muri 5-, 9-, 12- cyangwa 15-V
sisitemu kandi ifite imbaraga za tristoriste.Uwiteka
ibisohoka voltage irashobora gushirwa hanze ukoresheje résistor
