Guhindura

Igikoresho cyo guhinduranya ni voltage igenzura ikoresha ibintu byo guhinduranya kugirango ihindure amashanyarazi yinjira muri voltage ya pulsed, hanyuma igahinduka neza ikoresheje capacator, inductors, nibindi bintu.
Imbaraga zitangwa kuva mubyinjira mubisohoka uhindura ON switch (MOSFET) kugeza voltage yifuzwa igeze.
Iyo ibisohoka voltage igeze ku gaciro kateganijwe ibintu byahinduwe byahinduwe OFF kandi nta mbaraga zinjiza zikoreshwa.
Gusubiramo iki gikorwa kumuvuduko mwinshi bituma bishoboka gutanga voltage neza kandi hamwe nubushyuhe buke.

Ibisobanuro kuri TPS54560B-Q1

TPS54560B-Q1 ni 60 V, 5 A, kumanura umugenzuzi hamwe na MOSFET yo murwego rwo hejuru.Igikoresho kirokoka imitwaro yamenetse igera kuri 65V kuri ISO 7637. Igenzura ryubu ritanga indishyi zoroshye zo hanze hamwe no guhitamo ibice byoroshye.Uburyo buke bwo gusimbuka impanuka bugabanya nta mutwaro utanga kuri 146 µA.Guhagarika ibintu bigabanuka kugeza kuri 2 µA mugihe ifasha pin ikururwa hasi.
Undervoltage lockout yashyizwe imbere kuri 4.3 V ariko irashobora kwiyongera ukoresheje pin ifasha.Ibisohoka voltage itangira ramp igenzurwa imbere kugirango itangire igenzurwe kandi ikureho ibicuruzwa.
Urwego runini rwo guhinduranya inshuro zituma haba imikorere cyangwa ingano yibigize hanze kugirango ibe nziza.Ibisohoka bisohoka ni bike byizunguruka.Inshuro inshuro nyinshi hamwe no guhagarika ubushyuhe birinda ibice byimbere ninyuma mugihe ibintu birenze urugero.
TPS54560B-Q1 iraboneka muri 8-terminal yazamuye ubushyuhe bwa HSOP PowerPAD ™.
