Zithunzi za TPS54335A
Banja la TPS5433xA la zipangizo ndi osinthika osinthika omwe ali ndi gawo lothandizira-voltage la 4.5 mpaka 28 V. Zidazi zimaphatikizapo FET yosakanikirana yotsika kwambiri yomwe imathetsa kufunikira kwa diode yakunja yomwe imachepetsa chiwerengero cha chigawo.
Kuchita bwino kumakulitsidwa kudzera mu 128-mΩ ndi 84-mΩ MOSFETs, IQ yochepa komanso kulumpha kwapang'onopang'ono pa katundu wopepuka.Pogwiritsa ntchito pini yolumikizira, kutsekeka kwamagetsi kumachepetsedwa kukhala 2 μA.Chosinthira chotsikirapo (chopondapo) chimapereka malamulo olondola a katundu wosiyanasiyana omwe ali ndi chidziwitso chamagetsi choyendetsedwa bwino chomwe ndi 1.5% kuposa kutentha.
Kuchepetsa kwaposachedwa kwapakatikati pa MOSFET yam'mbali kumateteza banja la zida za TPS5433xA pamalo ochulukirachulukira ndipo kumakulitsidwa ndi malire apano omwe amalepheretsa kuthawa komwe kulipo.Njira yocheperako yocheperako imayimitsa MOSFET yambali yotsika kuti mupewe kuchulukirachulukira kwapano.Chitetezo cha hiccup chimayambika ngati vuto la overcurrent likupitirirabe kwa nthawi yayitali kuposa nthawi yokonzedweratu.Kuzimitsa kwa kutentha kumalepheretsa chipangizocho pamene kutentha kwa kufa kumadutsa pakhomo ndikupangitsa chipangizocho kachiwiri pambuyo pa nthawi yopangira kutentha.
1. Kodi ogwira ntchito m'dipatimenti yanu ya R & D ndi ndani?Kodi ziyeneretso zanu ndi zotani?
-R & D Mtsogoleri: pangani dongosolo la nthawi yayitali la R & D ndikumvetsetsa momwe kafukufuku ndi chitukuko;Kuwongolera ndi kuyang'anira dipatimenti ya r&d kuti ikwaniritse njira zamakampani ndi mapulani apachaka a R&D;Kuwongolera kupita patsogolo kwa chitukuko cha mankhwala ndikusintha dongosolo;Khazikitsani gulu labwino kwambiri la kafukufuku wazinthu ndi chitukuko, kufufuza ndi kuphunzitsa ogwira ntchito zaukadaulo.
Woyang'anira R & D: pangani mankhwala atsopano a R & D ndikuwonetsa kuthekera kwa dongosolo;Kuyang'anira ndi kuyang'anira momwe ntchito ya R&d ikuyendera;Fufuzani zachitukuko chazinthu zatsopano ndikupereka mayankho ogwira mtima malinga ndi zomwe makasitomala amafuna m'magawo osiyanasiyana
Ogwira ntchito ndi R&d: sonkhanitsani ndikusankha zofunikira;Mapulogalamu apakompyuta;Kuyesa, kuyesa ndi kusanthula;Konzani zida ndi zida zoyeserera, zoyeserera ndi kusanthula;Lembani deta yoyezera, pangani mawerengedwe ndikukonzekera ma chart;Chitani kafukufuku wamawerengero
2. Kodi lingaliro lanu la kafukufuku ndi chitukuko ndi chiyani?
- Lingaliro lazinthu ndi kusankha kwazinthu ndikuwunika tanthauzo lazinthu ndi kapangidwe ka pulani ya projekiti ndi kuyezetsa kwachitukuko ndikutsimikizira kukhazikitsidwa kwa msika
