Imiyoboro Yumuzunguruko Yumudugudu Utanga Ibishya kandi byumwimerere Muri Stock Bom Service TPS22965TDSGRQ1

Guhindura imizigo ni kubika umwanya, guhuza imbaraga.Ihinduranya irashobora gukoreshwa kugirango 'uhagarike' sisitemu ishonje imbaraga (mugihe muburyo bwo guhagarara) cyangwa kuri point-of-load-control kugirango byorohereze ingufu zikurikirana.Guhindura imizigo byakozwe mugihe telefone zigendanwa zamenyekanye;nkuko terefone yongeyeho imikorere myinshi, basabaga imbaho ​​zumuzunguruko mwinshi kandi umwanya wabaye muke.Guhindura imitwaro ihuriweho ikemura iki kibazo: gusubiza umwanya wibibaho kubashushanya mugihe uhuza imikorere myinshi.

Ni izihe nyungu zo guhuza imitwaro ihuriweho ugereranije n'umuzunguruko wihariye?

Igisubizo gisanzwe kigizwe na P-umuyoboro wicyuma cya oxyde semiconductor yumurima wa transistor (MOSFET), umuyoboro wa N-MOSFET, hamwe no gukurura.Mugihe iki ari igisubizo cyemejwe cyo guhindura amashanyarazi, gifite ikirenge kinini.Ibindi bisubizo byoroshye birahari ubu, nko guhinduranya imitwaro nka Texas Instruments TPS22915 - bafite ikirenge kiri munsi ya 1mm2!Igishushanyo cya 2 cyerekana kugereranya ishyirwa mubikorwa ryumukiriya umwe niki gisubizo cya TI, cyatumye TPS22968 igabanya ibirenge byayo hejuru ya 80% mugihe ihuza byinshi nkibipimo bigenzurwa nigipimo cyihuta kandi gisohoka vuba.
