Zithunzi za TPS62147
Ma TPS62147 ndi TPS62148 ndiwothandiza kwambiri komanso osavuta kugwiritsa ntchito osinthira DC/DC, kutengera DCS-Control™Topology.Ma voliyumu osiyanasiyana a 3-V mpaka 17-V amawapangitsa kukhala oyenera ma Li-Ion amitundu yambiri komanso njanji yapakatikati ya 12-V.Zipangizozi zimapereka 2-A mosalekeza kutulutsa pano.Amalowetsani Mode Save Power ponyamula katundu wopepuka kuti asunge magwiridwe antchito pamtundu wonsewo.Ndi izi, ndizoyenera kugwiritsa ntchito zomwe zimafunikira magwiridwe antchito olumikizidwa, monga PC yamafakitale ndi kuyang'anira makanema.Pini ya MODE itatsikira pansi, switchingfrequency imasinthidwa yokha kutengera zomwe zatuluka komanso zotulutsa ndi zotulutsa.Njirayi imatchedwa Automatic Efficiency Enhancement (AEE™) ndipo imasunga kusinthika kwakukulu pamayendedwe onse.TPS62147, TPS62148 imapereka kulondola kwa 1% kutulutsa kwavoltage mumayendedwe a PWM motero kumathandizira kupanga magetsi olondola kwambiri.Pini ya FSEL imalola kuyika ma frequency osinthika mumachitidwe okakamiza a PWM a 1.25 MHz kapena 2.5 MHz, motsatana.
Nthawi yocheperako ndi 18 µA.Mumode yotsekera pomwe pano ndi 1µA.
Zidazi zilipo ngati zosinthika, zoyikidwa mu VQFNpackage ya 3-mm × 2-mm.
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
