Ibisobanuro kuri LM22672
Igenzura rya LM22672 ritanga imirimo yose ikenewe kugirango dushyire mubikorwa imbaraga za voltage ndende-hasi (buck) igenzura ukoresheje byibuze ibice byo hanze.Ibi byoroshye gukoresha kugenzura bikubiyemo 42 V N-umuyoboro wa MOSFET uhindura ubushobozi bwo gutanga kugeza kuri 1 A yumuzigo.Umurongo uhebuje no kugenzura imitwaro hamwe nubushobozi buhanitse (> 90%) biragaragara.Igenzura ryumubyigano ritanga igihe gito mugihe, cyemerera igipimo kinini hagati yinjiza nibisohoka.Indishyi zimbere zisobanura ko uyikoresha adafite akazi katoroshye ko kubara ibice byindishyi.Ibisubizo 5 V bisohoka nibishobora guhinduka voltage ihari irahari.
Ubusanzwe guhinduranya inshuro zashyizwe kuri 500 kHz yemerera ibice bito byo hanze nibisubizo byiza byigihe gito.Mubyongeyeho, inshuro zishobora guhindurwa hejuru ya 200 kHz kugeza kuri 1 MHz hamwe na rezistor imwe yo hanze.Ihindagurika ryimbere rishobora guhuzwa nisaha ya sisitemu cyangwa kuri oscillator yundi mugenzuzi.Ibisobanuro bishoboza kwinjiza byorohereza kugenzura no kugenzura imbaraga za sisitemu.Muburyo bwo guhagarika umugenzuzi ashushanya 25 µA gusa (ubwoko).Guhindura byoroshye-gutangira ibintu bitangwa binyuze muguhitamo ubushobozi bumwe bwo hanze.LM22672 nayo yubatswe muguhagarika ubushyuhe, hamwe no kugabanya kurinda imitwaro irenze impanuka.
LM22672 ni umwe mubagize umuryango wa Texas Instruments 'SIMPLE SWITCHER®.Igitekerezo cya SIMPLE SWITCHER® gitanga uburyo bworoshye bwo gukoresha igishushanyo cyuzuye ukoresheje umubare muto wibigize hanze hamwe nigikoresho cya TI WEBENCH®.Igikoresho cya TI cya WEBENCH® gikubiyemo ibintu nko kubara ibice byo hanze, kwigana amashanyarazi, kwigana ubushyuhe, hamwe no kubaka-Byubatswe muburyo bworoshye.
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
