Chithunzi cha TPS548B22
Chipangizo cha TPS548B22 ndi chosinthira chandanda chimodzi chokhala ndi chosinthira pa nthawi, D-CAP3 mode control.Amapangidwa kuti azilondola kwambiri, kuchita bwino kwambiri, kuyankha kwakanthawi kochepa, kosavuta kugwiritsa ntchito, kuwerengera kwapang'onopang'ono kwazinthu zakunja, komanso makina ogwiritsira ntchito mphamvu zamlengalenga.
Chipangizochi chimakhala ndi mphamvu zosiyanitsira, ma TI ophatikizika a FET okhala ndi 4.1 mΩ kukana komanso kutsika kwapambali kwa 1.9 mΩ.Chipangizochi chimakhalanso ndi 0.5% yolondola, 0.9-V yotchulidwa ndi kutentha kozungulira pakati pa -40 ° C ndi + 125 ° C. Zomwe zimapikisana nazo zikuphatikizapo: kuwerengera kochepa kwambiri kwa chigawo chakunja, kulamulira kolondola kwa katundu ndi ndondomeko ya mzere, kutulutsa mphamvu ya magetsi kuyika kulondola, auto- kudumpha kapena FCCM mode ntchito, ndi internalsoft-start control.
Chipangizo cha TPS548B22 chikupezeka mu phukusi la 7 mm × 5 mm, 40-pin, LQFN-CLIP (RVF) phukusi (RoHs exempt).
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
