♠ TPS61196-Q1 6-Ikurikiranya 400-mA Umushoferi WLED hamwe na PWM Yigenga Yigenga Kuri buri murongo
TPS61196-Q1 itanga igisubizo gihujwe cyane kumodoka LCD yamurika hamwe nibikorwa byigenga bya PWM bigabanya kuri buri mugozi. Iki gikoresho nuburyo bugezweho butezimbere umugenzuzi utwara imirongo igera kuri itandatu ya WLED hamwe na LED nyinshi murukurikirane. Buri mugozi ufite ibyigenga byigenga bitanga LED ihindagurika kuva kuri 50 mA kugeza kuri 400 mA muri ± 1.5% ihuye neza. Umuvuduko ntarengwa kuri sink iriho urashobora gutegurwa murwego rwa 0.3 V kugeza 1 V kugirango uhuze na LED igezweho. Iyinjizwa rya voltage intera kubikoresho ni kuva 8 V kugeza 30 V.
TPS61196-Q1 ihindura imbaraga zo kugenzura ibicuruzwa biva mu mahanga mu buryo bwikora kugira ngo bitange gusa imbaraga zisabwa n’umugozi wa LED hamwe n’umuvuduko munini w’imbere wongeyeho hiyongereyeho ingufu nkeya zisabwa kuri iyo mugozi wa IFB pin, bityo bikanoza neza umushoferi. Guhindura inshuro zayo byateguwe na rezistor yo hanze kuva 100 kHz kugeza 800 kHz.
TPS61196-Q1 ishyigikira urumuri rwa PWM rutagaragara. Buri mugozi ufite ibyigenga byigenga bya PWM. Mugihe cya PWM icuramye, urumuri rwa LED rufunguye cyangwa ruzimya kuri frequency na cycle cycle bigenwa nikimenyetso cya PWM cyo hanze. Umuyoboro wa PWM uri hagati ya 90 Hz na 22 kHz.
TPS61196-Q1 ikomatanya kurinda birenze urugero, ibisohoka bigufi birinda imiyoboro, ISET kurinda bigufi-hasi, kurinda diode no gukingira bigufi, kurinda LED gufungura no kugufi, hamwe no guhagarika ubushyuhe bukabije. Mubyongeyeho, TPS61196-Q1 irashobora kumenya pin ya IFB mugufi kugirango ikingire umurongo wa LED. Igikoresho kandi gitanga porogaramu zishobora kwinjizwa munsi yumubyigano no gusohoka kurenza urugero.
