LM5165YDRCR Zamagetsi Zigawo za IC Integrated Chip mu Stock

Kufotokozera mwachidule:

Chipangizo cha LM5165 ndi chophatikizika, chosavuta kugwiritsa ntchito, 3-V mpaka 65-V, chosinthira chamtundu wocheperako wa IQ chowongolera bwino kwambiri pamagetsi ambiri olowera ndikunyamula ma osiyanasiyana apano.Ndi ma MOSFET amphamvu ophatikizika am'mbali komanso otsika, mpaka 150-mA yamagetsi otulutsa atha kuperekedwa pamagetsi osasunthika a 3.3 V kapena 5 V kapena pakutulutsa kosinthika.Chosinthiracho chidapangidwa kuti chikhale chosavuta kugwiritsa ntchito pomwe chimapereka zosankha kuti ziwongolere ntchito zomwe mukufuna.Mawonekedwe a Pulse Frequency Modulation (PFM) amasankhidwa kuti azitha kuyendetsa bwino kwambiri pakulemetsa kapena kuwongolera nthawi zonse (COT) pafupipafupi pafupipafupi.Madongosolo owongolera onsewa safuna kubwezeredwa kwa loop pomwe akupereka mzere wabwino kwambiri ndi kuyankha kwakanthawi kochepa komanso PWM yaifupi pa nthawi yosinthira masitepe akuluakulu.

MOSFET yapamwamba kwambiri ya P-channel imatha kugwira ntchito mozungulira 100% pamagetsi otsika kwambiri ndipo safuna capacitor ya bootstrap pagalimoto.Komanso, malire omwe akhazikitsidwa pano amatha kusinthika kuti akwaniritse kusankha kwa inductor pazofunikira zinazake zapano.Zosankha zosinthira nthawi zoyambira zimaphatikizapo kuchedwetsa pang'ono (palibe zoyambira zofewa), zokhazikika mkati (900 µs), ndikuyamba kofewa kwakunja pogwiritsa ntchito capacitor.Chizindikiro cha PGOOD chotseguka chitha kugwiritsidwa ntchito potsata ndondomeko, kupereka malipoti olakwika, ndi kuwunika kwamagetsi.LM5165 buck converter imapezeka mu pini 10, 3-mm × 3-mm, phukusi la VSON-10 lopangidwa ndi thermally ndi 0.5-mm pitch pitch.

Kusintha Owongolera

1. Kodi Switching Regulators ndi chiyani:
Voltage regulator ndi chipangizo chomwe chimapangitsa kuti mphamvu yamagetsi ikhale yokhazikika ndipo imakhala ndi ma voltage regulator circuit, control circuit, ndi servo motor.Pamene athandizira voteji kapena katundu kusintha, ndi chowongolera kulamulira dera zitsanzo, kuyerekeza ndi amakulitsa, ndiyeno amayendetsa servo galimoto atembenuza kuti udindo wa owongolera mpweya burashi kusintha.Zimapangitsa kuti mphamvu yamagetsi ikhale yosasunthika pongosintha kuchuluka kwa ma coil.
Chowongolera chosinthira chimagwiritsidwa ntchito kupanga magetsi otulutsa powongolera transistor kuti asinthe pakati pa ON state, ndi OFF boma komanso ndi zida zosungira mphamvu (ma capacitors ndi inductors) kuti magetsi azikhala okhazikika.Zimasinthidwa ndikusintha nthawi yosinthira malinga ndi zitsanzo za mayankho amagetsi otulutsa.

Chiyambi cha ntchito

Voltage regulator ndi mtundu wamagetsi opangira magetsi kapena zida zamagetsi zomwe zimatha kusintha voliyumu yotulutsa.Udindo wamagetsi owongolera magetsi ndikusinthasintha osati kutengera zofunikira za zida zamagetsi kuti zikhazikitse voteji yamagetsi mumtundu wake wamtengo wapatali kuti mabwalo osiyanasiyana kapena zida zamagetsi zizigwira ntchito moyenera pamagetsi ovotera.

Kuchuluka kwa ntchito

Magetsi owongolera amatha kugwiritsidwa ntchito kwambiri m'mabizinesi akumafakitale ndi migodi, minda yamafuta, njanji, malo omanga, masukulu, zipatala, kafukufuku wasayansi, ndi malo ena omwe amafunikira kukhazikika kwamagetsi.Amasinthidwanso ndi makompyuta apakompyuta, zida zamakina olondola, makompyuta a tomography (CT), zida zolondola, zida zoyeserera, zowunikira zonyamula, zida zotumizidwa kunja, mizere yopanga, ndi zida zina.Kuphatikiza apo, chowongolera chamagetsi ndichoyeneranso kutsika kwamagetsi otsika kapena okwera kwambiri, kusinthasintha kumapeto kwa netiweki yamagetsi otsika a ogwiritsa ntchito, komanso kusintha kwa zida zamagetsi.Voltage regulator ndiyoyenera kwambiri pazofunikira zonse za grid waveform voltage stabilization yamalo amagetsi.Mphamvu zowongolera mphamvu zowonjezera zimatha kulumikizidwa ndi matenthedwe, ma hydraulic, ndi ma jenereta ang'onoang'ono.

Gulu

Malinga ndi mitundu yosiyanasiyana ya zotulutsa zowongolera, chowongolera nthawi zambiri chimagawidwa kukhala AC regulator (AC voltage stabilization power supply) ndi DC regulator (DC voltage stabilization power supply) magawo awiri.
AC Voltage regulator: Voltage regulator ili ndi makumi akulu mpaka masauzande a ma kilowatts a AC voltage regulator, ndikupereka mphamvu zazikulu zoyesera ndi mafakitale, zida zamankhwala.Palinso magetsi ang'onoang'ono a AC owongolera ma watts ochepa mpaka ma kilowatts ochepa, omwe ali ma laboratories ang'onoang'ono kapena zipangizo zapakhomo kuti apereke mphamvu zapamwamba.
Owongolera a DC: Malinga ndi momwe ma chubu osinthira amagwirira ntchito, owongolera a DC nthawi zambiri amagawidwa m'magulu awiri: owongolera ndi kusintha.Kusintha kwa regulator rectifier, kusalaza kozungulira kumakhala ndi mtundu wolowera capacitor ndi kutsamwitsa koyilo yolowera mitundu iwiri, iyenera kusinthika molingana ndi njira yoyendetsera dera yosinthira.Mtundu wolowetsa coil umagwiritsidwa ntchito posinthira zowongolera zotsika, pomwe mtundu wolowetsa capacitor umagwiritsidwa ntchito powongolera zowongolera.
Izi ndi poyambira-pansi Converter.
