Diode Inc. irashaka ko umugenzuzi mushya abera porogaramu aho imbaraga zihoraho cyangwa amashanyarazi ahoraho asabwa gutwara disikuru n'amatara.Kuruhande rwa LCD, ibi birashobora kubamo gukoresha nkumushoferi winyuma kuri TV ya LCD, monitor ya LCD, hamwe na panne yerekana.Kuruhande rwa LED, ibyo birashobora gusobanura gukoresha nkumushoferi wa LED kumashanyarazi yubucuruzi.
Igikoresho cyakira voltage yinjira kuva kuri 9V kugeza 40V.Ibi birayemerera guhuza byoroshye na voltage zitandukanye zisanzwe zitangwa, nka 12V, 24V, na 36V, nta bindi bikoresho cyangwa gutakaza imikorere.
Urwego rwa dimming rugenzurwa na digitale ya PWM (pulse ubugari bwa pulse), ihindurwamo voltage igereranya kugirango igenzure neza.AL3353 irashobora gushyigikira ibimenyetso bya PWM hamwe numurongo uri hagati ya 5kHz kugeza 50kHz.
Byongeye kandi, AL3353 ikomeza guhuza ubushyuhe n'ubushyuhe butandukanye.Ibi bigerwaho hifashishijwe ishyirwa mubikorwa rya Diode 'dinamike umurongo wo kwishyura indishyi, ikoresha offset yo guhagarika ibicuruzwa.
AL3353 ikubiyemo umushoferi wa PWM ukoresha umushoferi ukoresha uburyo bugezweho hamwe nigikorwa cyagenwe cyagenwe kugirango agenzure LED.Umuyoboro wa LED unyura mumyumvire yo hanze.Umuvuduko ukabije wunvikana noneho ugereranwa nurwego rwa 400mV.Itandukaniro riri hagati ya voltage zombi zikoreshwa mugucunga impiswi yubugari bwumuriro wamashanyarazi, no kwemerera kugenzura imiyoboro inyura muri LED.
AL3353 irashobora kandi gukoreshwa mubihe bisaba kugenzura ingufu za voltage, aho kugenzura ibyasohotse.Irabikora mugupima hamwe numuyoboro utanga ibitekerezo uhuza ibikoresho bisohoka.
Kugirango wirinde hamwe na LED igenzura, AL3353 ikubiyemo ibintu bimwe byingenzi biranga umutekano.Muri byo harimo:
AL3353 irashobora gusimbuza ibice byinshi byihariye kandi irashobora kugabanya ibiciro bya BOM, kimwe no kugabanya umwanya wibibaho hamwe nubunini bwayo buto:
Urebye iki gice gifite akamaro, ntabwo bitangaje kuba hari abandi binjira muriki gice.Kandi, mugihe AL3353 itanga umusaruro umwe, abayikora bamwe batanga ibice hamwe nibisubizo bine.Dore bike:
