Ibisobanuro kuri TPS548B22
Igikoresho cya TPS548B22 nigikoresho cyoroheje gihinduranya gihuza nigihe, D-CAP3 igenzura.Yashizweho kubwukuri buhanitse, gukora neza, gusubiza byihuse, kworohereza-gukoresha, kubara ibintu bike byo hanze, hamwe na sisitemu yumuriro.
Iki gikoresho kirimo imyumvire itandukanye, TI ihuriweho na FETs hamwe na-hejuru-irwanya-4.1 mΩ hamwe na-munsi-yo kurwanya-1,9 mΩ.Igikoresho alsofeature neza neza 0.5%, 0.9-V yerekanwe hamwe nubushyuhe bwibidukikije hagati ya –40 ° C na + 125 ° C. Ibiranga irushanwa birimo: kubara ibintu biri hasi cyane kubara, kugenzura imizigo neza na lineregulation, gusohora voltage neza neza, auto- gusimbuka cyangwa imikorere yuburyo bwa FCCM, hamwe no kugenzura imbere.
TPS548B22device iraboneka muri 7 mm × 5 mm, 40-pin, LQFN-CLIP (RVF) pack (RoHs isonewe).
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
