Integrated boost switch
Kuthekera koyambira kolipiritsidwa
Malire osinthika opitilira muyeso ndi chipukuta misozi
Kuchulukitsa, kutsika kwamagetsi, UVLO ndi chitetezo cha kutentha kwambiri
Imathandizira ma capacitor onse a ceramic
Open-drain power chizindikiro chabwino
Ikuphatikiza ukadaulo wa NexFET™ power block
Phukusi la 22-pin QFN (DQP) lokhala ndi PowerPAD™
Zithunzi za TPS53319
Zida za TPS53318 ndi TPS53319 ndi D-CAP mode, 8-A kapena 14-A synchronous switchers yokhala ndi ma MOSFET ophatikizika.Amapangidwa kuti azigwiritsidwa ntchito mosavuta, kuwerengera kwapang'onopang'ono kwazinthu zakunja, komanso makina ogwiritsira ntchito mphamvu zamlengalenga.
Zidazi zimakhala ndi 1% yolondola, 0.6-V yotchulidwa, ndi kusintha kophatikizana kowonjezera.Zitsanzo za zinthu zopikisana zikuphatikiza: 1.5-V mpaka 22-V wide conversion input input range, otsika kwambiri a part part count, D-CAP™ mode control for super fast transent, auto-skip mode operation, internal-start control control, selectable pafupipafupi, ndipo palibe chifukwa cholipira.
Ma voliyumu osinthika amachokera ku 1.5 V mpaka 22 V, voteji yamagetsi amachokera ku 4.5 V mpaka 25 V, ndipo kuchuluka kwa voteji kumachokera ku 0.6 V mpaka 5.5 V.
Zipangizozi zimapezeka mu phukusi la 5 mm x 6 mm, 22-pin QFN phukusi ndipo zimatchulidwa kuyambira -40 ° C mpaka 85 ° C.
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
