♠ TPS61193 Imikorere-Imiyoboro itatu-Imiyoboro itatu LED
TPS61193 nubushobozi buhanitse, buke-EMI, byoroshye-gukoresha-LED umushoferi hamwe nubworoherane kugirango ushyigikire ibintu byinshi. Ifite ibyuma bitatu bihanitse-bigezweho bishobora guhuzwa kubushobozi bugezweho.
TPS61193 ifite DC-DC ihuriweho hamwe ishigikira ibikorwa byombi na SEPIC. Ihindura ifite imiyoboro iva mu kirere igenzurwa na LED igezweho yo mu cyumba cyo hejuru. Iyi mikorere igabanya ingufu zikoreshwa muguhindura voltage kurwego rwo hasi bihagije mubihe byose. Kuri EMI igenzura DC-DC ihindura ishyigikira gukwirakwiza spekure yo guhinduranya inshuro hamwe no guhuza hanze hamwe na pin yabigenewe.
TPS61193 ifite amashanyarazi yagutse kuva kuri 4.5 V kugeza 40 V kugirango ashyigikire bikomeye ubwoko butandukanye bwa porogaramu. TPS61193 ihuza ibintu byinshi byerekana amakosa. Igikoresho gishyigikira PWM kumurika igipimo cya 10 000: 1 kuri 100-Hz yinjiza PWM inshuro.
• Kwinjiza voltage ikora 4.5 V kugeza 40 V.
• Ibice bitatu bihanitse cyane
- Guhuza ubu 1% (bisanzwe)
- LED Ikurikiranya kugeza kuri mA 100 kumuyoboro
- Ibisubizo birashobora guhuzwa hanze kubushobozi buhanitse
• Umubare mwinshi wa 10 000: 1 kuri 100 Hz
• Kwinjiza imbaraga / SEPIC kumashanyarazi ya LED
- Umuvuduko usohoka kugeza 45 V.
–Guhindura inshuro 300 kHz kugeza kuri 2.2 MHz
- Guhindura ibyinjira byinjira
- Gukwirakwiza ibintu kuri EMI yo hepfo
• Ibintu byinshi byerekana amakosa
- Ibisohoka nabi
- Injiza voltage OVP, UVLO, na OCP
- Fungura kandi bigufi LED gutahura amakosa
- Guhagarika ubushyuhe
• Umubare ntarengwa wibigize hanze
Sisitemu yo kumurika inganda muburyo bwo kugenzura
• Inganda PC
• Ibikoresho byo gupima no gupima
