Ibiranga LP8867-Q1
- AEC-Q100 Yujuje ibyangombwa byo gukoresha imodoka:
- Icyiciro cy'ubushyuhe icyiciro 1:
- –40 ° C kugeza kuri + 125 ° C, T.A
- Umutekano ukora
- Inyandiko zirahari kugirango zifashe sisitemu yumutekano ikora
- 3-, 4-Umuyoboro 120-mA urohama
- Ikigereranyo cyo hejuru cyane cya 10 000: 1 kuri 100 Hz
- Guhuza ubu 1% (bisanzwe)
- LED Ikurikiranya kugeza kuri mA 120 kumuyoboro
- Ibisohoka birashobora guhurizwa hanze kugirango bigezweho hejuru kumurongo
- Kwinjiza hamwe hamwe na SEPIC ihindura imbaraga za LED imbaraga
- Iyinjiza ya voltage ikora 4.5 V kugeza 40 V.
- Umuvuduko usohoka kugeza 45 V.
- Kwinjiza 3.3-Guhindura FET
- Guhindura inshuro 300 kHz kuri 2.2 MHz
- Guhindura syncronisation yinjiza
- Gukwirakwiza ibintu kuri EMI yo hepfo
- Kumenya amakosa no kurinda
- Ibisohoka
- Injiza voltage OVP, UVLO na OCP
- Kuzamura SW OVP no gusohora OVP
- LED ifunguye kandi mugufi gutahura amakosa
- Imbaraga-Umurongo FET igenzura kurinda bisi
- Automatic LED igabanuka hamwe nubushyuhe bwo hanze
- Guhagarika ubushyuhe
Ibisobanuro kuri LP8867-Q1
LP8867-Q1, LP8869-Q1 ni imodoka ihuriweho cyane, EMI nkeya, byoroshye-gukoresha-LED umushoferi hamwe na DC-DC.Guhindura DC-DC bifasha kuzamura no gukora uburyo bwa SEPIC.Igikoresho gifite ibyuma bine cyangwa bitatu bihanitse-bigezweho bishobora guhurizwa hamwe kubushobozi bugezweho.
Ihindura DC-DC ifite imiyoboro ihindagurika yo kugenzura ibintu ishingiye kuri LED imbere ya voltage.Iyi mikorere igabanya ingufu zikoreshwa muguhindura voltage kurwego rwo hasi bihagije mubihe byose.Kugabanya EMI DC-DC ishyigikira gukwirakwiza spekure yo guhinduranya inshuro hamwe no guhuza hanze hamwe na pin yabigenewe.Umuyoboro mugari ushobora guhinduranya LP886x-Q1 kugirango wirinde guhungabana kumurongo wunvikana.
Iyinjiza rya voltage intera ya LP886x-Q1 ni kuva 4.5 V kugeza 40 V kugirango ishyigikire ibinyabiziga gutangira-guhagarara no guta ibintu.LP886x-Q1 ihuza ibintu byinshi byerekana amakosa.
