Semicon Yumwimerere Yuzuzanya Yumuzunguruko n123l1 BOM Urutonde rwa Serivisi Mububiko TPS7A5201QRGRRQ1 Ishusho Yerekanwe

ibisobanuro bigufi:

LDOs ishyirwa mubikorwa nkibisohoka byiza voltage LDOs cyangwa umusaruro mubi LDOs.ibintu byiza bisohora voltage LDOs (hasi yabataye ishuri): koresha imbaraga za tristoriste (nanone yitwa igikoresho cyohereza) nka PNP.iyi tristoriste yemerera kwiyuzuzamo kugirango uyigenzure ashobora kugira voltage nkeya cyane, mubisanzwe hafi 200mV;umusaruro mubi LDOs ukoresha NPN nkigikoresho cyo kohereza kandi ikora muburyo busa nibisohoka LDOs.Ibisohoka bibi LDO ikoresha NPN nkigikoresho cyayo cyohereza kandi ikora muburyo busa nigikoresho cya PNP cyibisohoka byiza LDO.

Ibyiciro

Impanuro Yagutse: Umuvuduko wa Dropout ni itandukaniro ntarengwa riri hagati yumubyigano winjiza na voltage isohoka bisabwa kugirango umuyobozi agumane ingufu zavuye muri 100mV hejuru cyangwa munsi yagaciro kayo.

Guhitamo igisubizo

Boost buri gihe ni amahitamo meza kuri DCDC, buck, niba guhitamo DCDC cyangwa LDO, kugereranya mubiciro, imikorere, urusaku, nibikorwa.

❶ Iyo ibyinjijwe nibisohoka voltage byegeranye, nibyiza guhitamo LDO igenzura, ishobora kugera kubikorwa byiza cyane.

Urugero: Abagenzuzi ba LDO bakunze gukoreshwa mubisabwa aho ingufu za batiri ya lithium-ion ihindurwamo ingufu za 3V zisohoka.Nubwo 10% byanyuma yingufu za bateri idakoreshwa, umugenzuzi wa LDO aracyemeza ko igihe kirekire cyo gukora bateri hamwe n urusaku ruke.

HenIyo ibyinjijwe na voltage nibisohoka voltage bitari hafi cyane, tekereza ubwoko bwa DCDC bwo guhinduranya kuko ibyinjira byinjira muri LDO bingana nibisohoka.Niba igitonyanga cya voltage ari kinini, ingufu zikoreshwa muri LDO nini cyane kandi imikorere ntabwo iri hejuru.

Ibiranga umurongo gakondo ugenzura

Igenzura risanzwe ryumurongo: mubisanzwe bisaba kwinjiza voltage Uin kuba byibuze 2V ~ 3V hejuru yumubyigano wavuyemo hafi (nka 78XX yuruhererekane rwa chip), naho ubundi ntizakora neza.Ariko ibintu nkibi birakabije.Niba 5V kugeza 3.3V, itandukaniro rya voltage hagati yinjiza nibisohoka ni 1.7V gusa, itujuje imikorere yimikorere isanzwe igenzura umurongo.Umuvuduko wacyo wa voltage kumurongo usanzwe ukoresheje umurongo wa NPN yingufu za transistor ni 2V.

Hamwe na MOS power transistors birashoboka gutanga voltage yo hasi cyane.Hamwe nimbaraga MOS, igabanuka ryumubyigano wonyine unyuze mubigenzuzi biterwa na ON irwanya imizigo yumuriro wibikoresho bitanga amashanyarazi.Niba umutwaro ari muto, igitonyanga cya voltage cyakozwe murubu buryo ni milivolts nkeya gusa.
