Ibisobanuro kuri TPS7A20
TPS7A20 ni ultra-nto, ntoya-ita (LDO) igenzura umurongo ushobora gutanga 300 mA yumusaruro usohoka.TPS7A20 yashizweho kugirango itange urusaku ruke, PSRR ndende, hamwe nuburemere buhebuje hamwe numurongo wigihe gito ushobora kuzuza ibisabwa na RF hamwe nizindi nzitizi zisa.Ukoresheje uburyo bushya bwo gushushanya, TPS7A20 itanga urusaku ruhebuje rudasanzwe hiyongereyeho capacitor y urusaku.TPS7A20 nayo itanga ibyiza byumuvuduko muke, birashobora kuba byiza kubikorwa bya batiri.Hamwe ninjiza ya voltage ya 1.6 V kugeza 6.0 V hamwe nibisohoka 0.8 V kugeza 5.5 V, TPS7A20 irashobora gukoreshwa muburyo butandukanye bwa porogaramu.Igikoresho gikoresha umurongo utomoye kugirango utange ibisobanuro ntarengwa bya 1.5% hejuru yumutwaro, umurongo, nubushyuhe butandukanye.
TPS7A20 igaragaramo imbere yoroheje-itangira kumanura inrush, bityo kugabanya kwinjiza voltage kugabanuka mugihe cyo gutangira.Igikoresho kirahagaze hamwe na capacitori ntoya, itanga ubunini buke muri rusange.
TPS7A20 ifite ubwenge bushoboza kwinjiza ibintu hamwe na rezo irwanya imbere imbere ituma LDO imugara nubwo EN pin isigaye ireremba kandi igafasha gukuraho ibice byo hanze bikoreshwa mugusunika EN pin.
1. Ni bande bakozi mu ishami rya R & D?Ni ubuhe bushobozi bwawe?
-R & D Umuyobozi: gutegura gahunda yigihe kirekire yikigo no gusobanukirwa icyerekezo cyubushakashatsi niterambere;Kuyobora no kugenzura ishami rishyira mubikorwa ingamba za sosiyete na gahunda ya R&D yumwaka;Kugenzura iterambere ryibicuruzwa no guhindura gahunda;Shiraho ibicuruzwa byiza byubushakashatsi niterambere, kugenzura no guhugura abakozi ba tekiniki bijyanye.
Umuyobozi wa R & D: kora ibicuruzwa bishya R & D hanyuma werekane ko bishoboka gahunda;Kugenzura no gucunga iterambere nubuziranenge bwakazi;Kora ubushakashatsi ku bicuruzwa bishya kandi utange ibisubizo bifatika ukurikije ibyo umukiriya asabwa mubice bitandukanye
Abakozi & gukusanya: gukusanya no gutondekanya amakuru yingenzi;Porogaramu ya mudasobwa;Gukora ubushakashatsi, ibizamini nisesengura;Tegura ibikoresho nibikoresho byo kugerageza, kugerageza no gusesengura;Andika amakuru yo gupima, gukora ibarwa no gutegura imbonerahamwe;Kora ubushakashatsi bwibarurishamibare
2. Niki gitekerezo cyawe cyo gukora ubushakashatsi nibitekerezo byiterambere?
- Igitekerezo cyibicuruzwa no guhitamo ibicuruzwa nibisobanuro byerekana ibicuruzwa nibishushanyo mbonera byumushinga no kugerageza ibicuruzwa bitezimbere no kwemeza isoko
