Ibisohoka Umuvuduko Ukwiye ± 1% hejuru ya T.Jurwego (uburyo bwa PWM)
Iyinjiza rya voltage Urwego: 3 V kugeza 17 V.
Guceceka Ibiriho 18 µBisanzwe
Umuvuduko usohoka kuva 0.8 V kugeza 12 V.
Guhindura Byoroheje-Gutangira
Ku gahato PWM cyangwa PWM / PFM
Guhindura inshuro ya 1.25MHz cyangwa 2.5 MHz muri PWM ku gahato
Ibisobanuro bishobotse kwinjiza byemewe
Umukoresha-Yasobanuye Undervoltage Ifunga
Gukurikirana neza 100%
Uburyo bw'inshingano
Kongera imbaraga mu buryo bwikora AEE ™
DCS-Igenzura ™ Topologiya
Gusohora Ibisohoka Bikora (TPS62148)
Kurinda HICCUP Kurinda Byinshi (TPS62147)
Imbaraga Zisohoka
Biboneka muri 2-mm × 3-mm ya VQFN
Ibisobanuro kuri TPS62147
TPS62147 na TPS62148 nibikorwa byiza kandi byoroshye-gukoresha-guhuza intambwe-hasi ya DC / DC ihindura, ishingiye kuri DCS-Igenzura ™ Topologiya.Ubwinshi bwinjiza voltage ya 3-V kugeza 17-V ituma bikwiranye na selile nyinshi Li-Ion aswell nka 12-V intera itanga intera.Ibikoresho bitanga 2-A bikomeza gusohoka.Iyinjizamo imbaraga zo kuzigama imbaraga zumutwaro kugirango ukomeze gukora neza murwego rwose.Hamwe nibyo, bikwiranye nibisabwa bisaba guhuza ibikorwa, nka PC yinganda no kugenzura amashusho.Hamwe na MODE pin yashyizwe hasi, guhinduranya ibintu byahinduwe mu buryo bwikora hashingiwe kubisohoka hamwe no kwinjiza no gusohoka.Ubu buhanga bwitwa Automatic Efficiency Enhancement (AEE ™) kandi bugakomeza gukora neza cyane murwego rwose.TPS62147, TPS62148 itanga 1% ya voltvoltage yukuri muburyo bwa PWM bityo igushoboza gushushanya amashanyarazi afite amashanyarazi menshi.Ipine ya FSEL yemerera gushiraho inshuro zo guhinduranya muburyo bwa PWM bwa 1.25 MHzor 2.5 MHz.
Ibisanzwe bituje ni 18 µA.Muburyo bwo guhagarika ikigezweho ni 1µA.
Ibikoresho birahari nka verisiyo ishobora guhinduka, ipakiye muri 3-mm × 2-mm VQFNpackage.
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
