- Kurinda VCC na Gate Drive Kurinda UVLO
- Kurinda Ubushyuhe bwo Kurinda hamwe na Hystereze
Kora Igishushanyo cyihariye Ukoresheje LM5160A Hamwe naWEBENCH®Igishushanyo mbonera
Ibisobanuro kuri LM5160
LM5160 / A ni 65-V, 2-Ihinduranya-intambwe-ihinduranya hamwe hamwe na MOSFETs yo mu mpande zombi.Guhuza n'imihindagurikire y'ikirere ku gihe cyo kugenzura ntibisaba ko habaho indishyi kandi bigashyigikira igipimo cyo hasi-hasi hamwe n'ibisubizo byihuse.Imbere yo kwisubiza imbere ikomeza ± 1% isohoka rya voltage igenga ubushyuhe bwimikorere yose.Theon-time iratandukanye muburyo bwo kwinjiza voltage bivamo guhora uhinduranya inshuro.
Imipaka yimisozi miremire irinda ibintu birenze urugero.Inzira ya Theundervoltage (EN / UVLO) itanga ibyigenga byigenga byinjira munsi ya volvoltagethreshold na hystereze.LM5160 / A yateguwe binyuze muri pin ya FPWM kugirango ikore muburyo bukomeza (CCM) kuva nta mutwaro ujya ku mutwaro wuzuye cyangwa guhita uhindura uburyo bwo guhagarika ibintu (DCM) ku mutwaro woroshye kugirango ukore neza.Igikorwa cya CCM ku gahato gishyigikira ibintu byinshi-bisohoka hamwe na porogaramu ya Fly-Buck ukoresheje inductor ihujwe.
LM5160A isangiye ibintu bimwe na pin iboneza nkaLM5160.Isoko ryo kubogama ryo hanze rishobora guhuzwa na VCC pin ya LM5160A muri Buck na Fly-Buckapplications.Ubu bushobozi bwinyongera bugabanya imbaraga za IC kandi bigatezimbere imikorere ya athigh voltage.
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
