Zithunzi za TPS62242
Chipangizo cha TPS6224x ndi chosinthira bwino kwambiri chosinthira DC-DC.Chipangizochi chimapereka kutulutsa kwa 300-mA pakadali pano kuchokera pa cell imodzi ya Li-Ion ndipo ndi yabwino kwa mapulogalamu onyamula batire monga mafoni am'manja ndi zida zina zonyamula.
Pokhala ndi ma voliyumu ambiri amtundu wa 2 V mpaka 6 V, chipangizochi chimathandiziranso ma cell awiri ndi atatu amchere, 3.3-V ndi 5-V njanji yamagetsi.
TPS6224x imagwira ntchito pafupipafupi 2.25-MHz ndikulowetsa njira yosungira mphamvu pamayendedwe opepuka kuti ikhale yogwira ntchito kwambiri pamtundu wonse wapano.
Njira yopulumutsira mphamvu imakonzedwa kuti ikhale yotsika voteji ripple.Pazinthu zokhala ndi phokoso lotsika, chipangizochi chitha kukakamizika kuti chilowe mumodeti yokhazikika-frequency pulse wide modulation (PWM) pokokera pini ya MODE m'mwamba.Mumayendedwe otsekera, kugwiritsa ntchito pano kumachepetsedwa mpaka 1 µA.TPS6224x imalola kugwiritsa ntchito ma inductors ang'onoang'ono ndi ma capacitor kuti akwaniritse kukula kochepa.
TPS6224x imagwira ntchito pa kutentha kwa mpweya waulere wa -40 ° C mpaka 85 ° C.Chipangizocho chimapezeka mu 5-pin SOT ndi 6-pin 2-mm × 2-mm WSON phukusi.
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
