Zithunzi za TPS630250
Ma TPS63025x ndi okwera kwambiri, otsika pang'ono osinthira ma buck-boost omwe akuyenera kugwiritsidwa ntchito pomwe magetsi olowera ndi okwera kapena otsika kuposa zomwe zatulutsa.Zotulutsa zimatha kukwera mpaka 2 A mu boost mode ndikukwera mpaka 4 A mu buck mode.Kuchuluka kwapakati pamasinthidwe kumangokhala pamtengo wa 4 A. TPS63025x imayang'anira voteji yotulutsa pamtundu wamagetsi wathunthu posinthana pakati pa buck kapena boost mode kutengera mphamvu yamagetsi yomwe imatsimikizira kusintha kosasinthika pakati pamitundu.Chosinthira cha buck-boost chimakhazikitsidwa ndi wowongolera pafupipafupi, pulse-width-modulation (PWM) pogwiritsa ntchito kuwongolera kolumikizana kuti apeze bwino kwambiri.Pamafunde otsika kwambiri, chosinthiracho chimalowa mu Power Save Mode kuti chikhale chogwira ntchito kwambiri pamtundu wathunthu wapanthawiyo.Pali pini ya PFM/PWM yomwe imalola wogwiritsa ntchito kusankha pakati pa machitidwe a PFM/PWM ndi kukakamiza PWM.Panthawi ya PWM, ma frequency okhazikika a 2.5 MHz amagwiritsidwa ntchito.Magetsi otulutsa amatha kusinthidwa pogwiritsa ntchito chogawa chakunja, kapena amakhazikika mkati mwa chip.Chosinthiracho chikhoza kuyimitsidwa kuti muchepetse kukhetsa kwa batri.Panthawi yotseka, katunduyo amachotsedwa ku batri.Chipangizocho chimayikidwa mu phukusi la WCSP la pini 20 la 1.766 mm × 2.086mm ndi phukusi la HotRod la 14-pini la 2.5 mm × 3mm.
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
