Zithunzi za LM22672
LM22672 switching regulator imapereka ntchito zonse zofunika kuti akhazikitse chowongolera chotsika kwambiri chamagetsi (buck) pogwiritsa ntchito zida zakunja.Chowongolera chosavuta kugwiritsa ntchitochi chimaphatikizapo chosinthira cha 42 V N-channel MOSFET chotha kupereka mpaka 1 A ya katundu wapano.Mzere wabwino kwambiri komanso malamulo onyamula katundu komanso magwiridwe antchito apamwamba (> 90%) amawonetsedwa.Kuwongolera kwamagetsi amagetsi kumapereka kwakanthawi kochepa pa nthawi, kulola chiyerekezo chokulirapo pakati pa ma voliyumu olowera ndi otulutsa.Kulipira kwa loop mkati kumatanthauza kuti wogwiritsa ntchito alibe ntchito yotopetsa yowerengera magawo amalipiro a loop.Kutulutsa kwa 5 V kosasunthika komanso zosankha zamagetsi zosinthika zilipo.
Kusinthasintha kosasintha kumayikidwa pa 500 kHz kulola tinthu tating'ono tating'ono takunja ndikuyankhidwa kwakanthawi kochepa.Kuphatikiza apo, ma frequency amatha kusinthidwa pamitundu yosiyanasiyana ya 200 kHz mpaka 1 MHz yokhala ndi chopinga chimodzi chakunja.The oscillator mkati akhoza synchronized kwa wotchi dongosolo kapena oscillator wa wowongolera wina.Kuwongolera kolondola kumathandizira kuphweka kwa zowongolera ndi kutsata mphamvu zamakina.Mumode yotsekera wowongolera amakoka 25 µA (mtundu).Chosinthika choyambira chofewa chimaperekedwa mwa kusankha capacitor imodzi yakunja.LM22672 idamanganso kutsekeka kwamafuta, komanso malire apano kuti atetezere pakuchulukira mwangozi.
LM22672 ndi membala wa banja la Texas Instruments 'SIMPLE SWITCHER®.Lingaliro la SIMPLE SWITCHER® limapereka zosavuta kugwiritsa ntchito mapangidwe athunthu pogwiritsa ntchito chiwerengero chochepa cha zigawo zakunja ndi chida chojambula cha TI WEBENCH®.Chida cha TI cha WEBENCH® chimaphatikizapo zinthu monga kuwerengera kwa chigawo chakunja, kayeseleledwe ka magetsi, kayeseleledwe ka matenthedwe, ndi ma board a Build-It kuti apangidwe mosavuta.
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
