Zida zamagetsi IC chip LM25118Q1MH/NOPB

Kufotokozera mwachidule:

LM25118 wide voltage range Buck-Boost switching regulator controller imakhala ndi ntchito zonse zofunika kuti agwiritse ntchito kwambiri, yotsika mtengo ya Buck-Boost regulator pogwiritsa ntchito zochepa zakunja.Buck Boost topology imasunga malamulo otulutsa mphamvu pomwe mphamvu yolowera imakhala yocheperako kapena yokulirapo kuposa mphamvu yotulutsa ndikupangitsa kuti ikhale yoyenera pamagalimoto.LM25118 imagwira ntchito ngati chowongolera chandalama pomwe voteji yolowera ndi yayikulu mokwanira kuposa mphamvu yamagetsi yomwe imayendetsedwa ndipo pang'onopang'ono imasintha kupita ku buck-boost mode pomwe mphamvu yolowera ikuyandikira zomwe zimatuluka.Njira yapawiri iyi imasunga malamulo pamitundu yambiri yolowera ndikusintha koyenera mumayendedwe a buck komanso kutulutsa kopanda glitch panthawi yakusintha.Chowongolera chosavuta kugwiritsa ntchitochi chimaphatikizapo madalaivala amtundu wapamwamba wa MOSFET ndi MOSFET yotsika kwambiri.Njira yowongolera ya chowongolera imatengera kuwongolera kwakanthawi kogwiritsa ntchito njira yotsatsira.Kuwongolera kwakanthawi koyeserera kumachepetsa kukhudzika kwa phokoso la pulse wide modulation circuit, kulola kuwongolera kodalirika kwamayendedwe ang'onoang'ono omwe amafunikira pakugwiritsa ntchito magetsi okwera kwambiri.Zina zowonjezera zachitetezo zikuphatikiza malire apano, kutseka kwamafuta, ndi kuyatsa.Chipangizochi chimapezeka mu phukusi lamphamvu la HTSSOP la pini 20 lokhala ndi cholumikizira cholumikizira kuti chithandizire kutenthedwa.

Automatic Drive

Monga ubongo wa galimoto yopanda munthu, chipangizo cha AI choyendetsa galimoto chodziyimira payokha chiyenera kukonza deta yopangidwa ndi masensa ambiri mu nthawi yeniyeni, ndipo imakhala ndi zofunikira kwambiri pa mphamvu ya kompyuta ya chip, kugwiritsa ntchito mphamvu ndi kudalirika.Pakalipano, chip chiyenera kukwaniritsa miyezo ya galimoto, choncho zimakhala zovuta kupanga.Pakadali pano, tchipisi toyendetsa pawokha makamaka chimaphatikizapo Nvidia Orin, Xavier ndi Tesla's FSD.

Smart Home System

Munthawi ya AIoT, chida chilichonse m'nyumba yanzeru chiyenera kukhala ndi malingaliro, malingaliro ndi ntchito zopangira zisankho.Kuti mukhale ndi chidziwitso chogwiritsa ntchito bwino pamawu anzeru, Chip AI ya mawu yalowa msika wam'mbali.Tchipisi za Voice AI ndizosavuta kupanga komanso zimakhala ndi kakulidwe kakang'ono.Tchipisi zoyimilira ndi Spitz TH1520 ndi
Yunzhi Sound Swift UniOne, etc.

Automatic Drive

IC, ndi semiconductor zigawo zikuluzikulu zopangira pamodzi, zomwe zimadziwikanso kuti Integrated Circuit (IC, Integrated Circuit).
Tchipisi zamagalimoto zimagawidwa m'magulu atatu: tchipisi tating'ono (MCU=Micro controller Unit), Power Semiconductor, Sensor.

Chip chogwira ntchito makamaka chimatanthawuza purosesa ndi chowongolera.Galimoto imatha kuyenda pamsewu popanda zomangamanga zamagetsi ndi zamagetsi kuti zitumize zidziwitso ndi kukonza deta.Dongosolo loyang'anira magalimoto makamaka limaphatikizapo dongosolo lamagetsi la thupi, kayendedwe ka magalimoto, dongosolo la powertrain, makina osangalatsa azidziwitso, makina oyendetsa okha ndi zina zotero.Pali zinthu zambiri zazing'ono pansi pa machitidwe awa.Kumbuyo kwa chinthu chilichonse chaching'ono ndi chowongolera, ndipo padzakhala chip chogwira ntchito mkati mwa wowongolera.
