Kuberako VF iranga agaciro kaLED, indangagaciro zimwe za VF zizahinduka hamwe nubushyuhe nubu, mubisanzwe ntibikwiranye nuburinganire. Ariko, mubihe bimwe na bimwe, tugomba gukemura ikibazo cyo gutwara ibiciro bya LED nyinshi murwego rumwe. Ibishushanyo birashobora gukoreshwa mubisobanuro.

Menya ko agaciro ka VF kagomba kugabanywamo amanota. LED ifite agaciro kamwe ka VF igomba gukoreshwa kubicuruzwa bimwe bishoboka. Igicuruzwa kirashobora kwemeza ko ikosa ririho muri 1mA kandi LED iri muburyo buhoraho.

Gukoresha triode ihuriweho irashobora kugumana ikigezweho cya buriLED ihamye. Izi nyabutatu zikorwa munsi yubushyuhe bumwe hamwe nuburyo bumwe process Agaciro kamwe gashobora kwemeza ko buri cyerekezo ari kimwe. Igice gihoraho gishobora gutegurwa murubu buryo ibisabwa ntabwo biri hejuru cyane. Umuvuduko uhamye cyangwa imbaraga za PWM zihamye zitwara triode ibogamye ya voltage kugirango igere kumurongo wibanze uhoraho.

Ukoresheje IC ifite ubunyangamugayo buhanitse nkisoko ihoraho yerekana isoko, R irashobora gushiraho IC isohoka. Iyo agaciro ka R kamaze kugenwa, karashobora gusimburwa nuburwanya buhamye. Gukoresha ibikoresho byinshi bya triode bihujwe birashobora kugabanya ikoreshwa rya IC, bityo bikagabanya ibiciro byibicuruzwa.

Umurongo muremure-imbaraga LED ihoraho isohoka irashobora gukoreshwa murwego rumwe. Mugushushanya ibicuruzwa, ntidushobora kubona IC yo gutwara hamwe numuyoboro munini. Mubisanzwe, ntibisanzwe kubona IC ifite nomero 2A cyangwa irenga, kandi IC ifite nomero 2A ntishobora gukoreshwa kumupaka. Impamvu yikiguzi cyibikorwa bya IC irenze 1a nuko imiyoboro ya MOS iri hanze, naho imiyoboro ya MOS yo hanze iragoye kandi kwizerwa kugabanuka. Igikorwa kibangikanye nuburyo bwiza bwo gushushanya.

Dd312 ibishushanyo mbonera bifatika byemewe kugirango bitware bitatu 6wled. Gushoboza ibimenyetso bya PWM bisaba kwigunga neza kugirango wirinde kwivanga hamwe nibibazo byubushobozi bwo gutwara. Umuvuduko utanga imbaraga ugomba kuba wujuje ibisabwa mubisobanuro, kandi ntukangiza EN pin hejuru cyane. Mubisanzwe, IC kwihanganira voltage bivuga umutwaro n'amashanyarazi. Niba nta cyerekana voltage ishimishije, nyamuneka nturenze 5V igishushanyo.

Kuri ubu bwoko bwo gutahura ,.LED ihorahoibinyabiziga bigezweho IC kumpera imwe ya LED nayo irashobora gushushanywa no kugendana. Mubyukuri, IC ikora yonyine kandi amaherezo ikorera hamwe murwego rumwe. Uburyo bwa DC-DC bukora kumurongo mwinshi. Twabibutsa ko imiterere ya PCB igomba kwirinda gushushanya. Akayunguruzo hamwe na bypass capacator bigomba kuba hafi ya IC, hanyuma imizigo yimizigo amaherezo ikazahuzwa.
