4-V mpaka 36-V yolowetsamo
2.5-A mosalekeza linanena bungwe panopa
Integrated synchronous rectification
Ulamuliro wamakono wamakono
Kusintha kochepa pa nthawi: 60 ns
2.1-MHz kusintha pafupipafupi ndi PFM ndi zosankha zokakamiza-PWM-mode (HSOIC)
2.1-MHz kusintha pafupipafupi ndi mokakamizidwa-PWM mode kokha (WSON)
Kulunzanitsa pafupipafupi ku wotchi yakunja
Malipiro amkati kuti agwiritse ntchito mosavuta
75-µA quiescent current popanda katundu
Kuyamba kofewa kukhala katundu wokhazikika
Kugwira ntchito mozungulira kwambiri kumathandizidwa
Mwatsatanetsatane yambitsani zolowetsa
Kutulutsa chitetezo chafupipafupi chokhala ndi hiccup mode
Chitetezo chamafuta
8-Pini HSOIC yokhala ndi phukusi la PowerPAD™
Phukusi la 12-Pini la WSON lonyowa lokhala ndi PowerPAD™

LMR23625 SIMPLE SWITCHER ndi yosavuta kugwiritsa ntchito 36-V, 2.5-A synchronous step-down regulator.Ndi zolowetsa zambiri kuchokera ku 4 V mpaka 36 V, chipangizocho ndi choyenera kugwiritsa ntchito mafakitale osiyanasiyana opangira magetsi kuchokera kuzinthu zosayendetsedwa.Peak-current-mode control amagwiritsidwa ntchito kuti apeze chipukuta misozi chosavuta chowongolera komanso kuchepetsa malire apano.Kutsika kwamphamvu kwa 75 µA kumapangitsa kuti ikhale yoyenera pamakina oyendera mabatire.Kutsekeka kotsika kwambiri kwa 2 µA kumatha kutalikitsa moyo wa batri.Kulipira kwa loop mkati kumatanthauza kuti wogwiritsa ntchito alibe ntchito yotopetsa yakupanga chipukuta misozi.Izi zimachepetsanso zigawo zakunja.
Chipangizocho chili ndi mwayi wosankha mawonekedwe a FPWM okhazikika kuti akwaniritse zotulutsa zazing'ono-voltage ripple pakulemetsa kopepuka.Banja lokulirapo la HSOIC likupezeka mu 1-A (LMR23610) ndi 3-A (LMR23630) zonyamula zosankha zaposachedwa pamapaketi ogwirizana ndi pini-to-pini omwe amalola masanjidwe osavuta, abwino kwambiri a PCB.Kuwongolera kolondola kumathandizira kuphweka kwa zowongolera ndi kutsata mphamvu zamakina.Zida zodzitchinjiriza zimaphatikizapo malire apano mozungulira-ndi-cycle, chitetezo chachifupi cha hiccup-mode ndi kutseka kwamafuta chifukwa cha kutha kwamphamvu kwambiri.
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
