Guhindura Abagenzuzi
Guhindura ibiyobora ni ubwoko bwumuzunguruko ushobora guhindura voltage ninjiza byinjira mumashanyarazi hamwe nibisohoka bikwiranye cyane no guha ingufu sisitemu itanga ingufu kuri.Ubu bwoko bwumuzunguruko nabwo buzwi nkuguhindura kandi nibyiza mugutunganya ingufu zihererekanwa hagati yibi bice byombi kugirango habeho imbaraga ziva mumashanyarazi zihoraho zitekanye mumipaka yumuzunguruko.Bakora kumurongo wo hejuru cyaneumurongo ugenzurakandi utange inyungu zo gucunga neza kandi bihendutse gucunga ingufu mugihe kirekire, kimwe no kuba akenshi bidasaba ubushobozi bwo hanze.
Ni ubuhe buryo bwo guhindura ibintu bukoreshwa?
Ubu bwoko bwabashinzwe kugenzura bukoreshwa kenshi muri selile imwe cyangwa selile nyinshi zikoreshwa na bateri ndetse no mubikoresho bya elegitoronike bikoreshwa na elegitoronike nka kamera ya digitale, imashini yimikino ikoreshwa, imashini igenzura nibindi byinshi.Inyungu nyamukuru yo gukoresha ibyo guhinduranya ibintu aho gukoresha umurongo ugenzura ni uko batanga uburinzi bwumuzunguruko mugufi kandi bakemeza ko birenze urugero na voltage ikingira.Nibyiza kandi kurinda sisitemu ya elegitoronike ubushyuhe burenze no kwangirika kwinshi.
Ubwoko bwo guhinduranya
Intambwe-Hejuru cyangwa Kuzamura Abagenzuzi - Ubu ni bwo buryo bwibanze bwo guhinduranya ibintu kandi bikoreshwa mu kongera ingufu za voltage
· Intambwe-Hasi cyangwa Buck-Boost Guhindura - Bagabanya cyangwa bahindura ibisohoka voltage kubijyanye na voltage yinjira

Ibisobanuro kuri LP87524J-Q1
LP87524B / J / P-Q1 yashizweho kugirango ihuze ibisabwa byo gucunga ingufu za progaramu zigezweho hamwe na platform mubikorwa bitandukanye byamashanyarazi.Igikoresho kirimo intambwe enye zimanuka DC-DC ihindura ibice, bigizwe nkibisubizo 4 byicyiciro kimwe.Igikoresho kiyobowe na I.2C-ihuza seriveri yimbere kandi mugushoboza ibimenyetso.
Igikorwa cyikora cya PFM / PWM (uburyo bwa AUTO) gikora neza cyane mugusohora kwinshi-bigezweho.LP87524B / J / P-Q1 ishyigikira amashanyarazi ya kure kugirango yishyure igabanuka rya IR hagati yumusaruro uva hamwe nu ngingo-yumutwaro (POL) bityo bikazamura ukuri kwumubyigano usohoka.Mubyongeyeho, isaha yo guhinduranya irashobora guhatirwa muburyo bwa PWM kandi ikanahuzwa nisaha yo hanze kugirango igabanye imvururu.
Igikoresho cya LP87524B / J / P-Q1 gishyigikira ibipimo-byapimwe bitarinze kongerwaho ibyiyumvo byo hanze-byunvikana.Mubyongeyeho, LP87524B / J / P-Q1 ishyigikira gahunda yo gutangira no gutangira gutinda no guhagarika gukurikiranwa hamwe kugirango bikurikirane ibimenyetso.Urukurikirane rushobora kandi gushiramo ibimenyetso bya GPIO kugenzura abagenzuzi bo hanze, guhinduranya imitwaro no gusubiramo ibintu.Mugihe cyo gutangira na voltage ihinduka, igikoresho kigenzura ibisohoka kugirango igabanye ibisohoka kugirango voltage igabanuke kandi muri in-rush.
