Ibisobanuro kuri TPS54140A
Igikoresho cya TPS54140A ni 42-V, 1.5-A, kugenzura hasi-hamwe na MOSFET yo murwego rwo hejuru.Igenzura-ryubu ritanga indishyi zoroshye zo hanze hamwe no guhitamo ibice byoroshye.Ubwoko bwa ripple-pulse gusimbuka uburyo bugabanya nta-mutwaro, ugenga ibicuruzwa bitangwa kugeza kuri 116 µA.Ukoresheje gukora pin, guhagarika isoko bigabanuka kugeza kuri 1.3 µA.
Undervoltage lockout yashyizwe imbere kuri 2.5 V, ariko irashobora kwiyongera ukoresheje pin.Ibisohoka voltage itangira ramp iyobowe na buhoro buhoro pin ishobora no gushyirwaho kugirango ikurikirane / ikurikirana.Gufungura imiyoboro yamashanyarazi yerekana neza ibisohoka biri muri 94% kugeza 107% bya voltage yizina.
Ingano nini yo guhinduranya inshuro zituma imikorere nubunini bwibikoresho byo hanze bigenda neza.Inshuro zisubira inyuma kandi guhagarika ubushyuhe birinda igice mugihe kirenze urugero.
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
