LM5176 55-V Wide VIN Daidaitacce 4-switch Buck-Boost Controller
LM5176 mai daidaitawa huɗu ne mai haɓaka buck-boost DC/DC mai ikon daidaita ƙarfin fitarwa a sama, ko ƙasa da ƙarfin shigarwar. LM5176 yana aiki akan kewayon ƙarfin shigarwa mai faɗi na 4.2 V zuwa 55 V (60-V cikakken iyakar) don tallafawa aikace-aikace iri-iri.
LM5176 yana amfani da sarrafa yanayin halin yanzu duka a cikin buck da haɓaka hanyoyin aiki don babban nauyi da ka'idojin layi. Ana tsara mitar sauyawa ta hanyar resistor na waje kuma ana iya aiki tare da siginar agogo na waje.
Na'urar kuma tana da aikin farawa mai laushi mai iya tsara shirye-shirye kuma tana ba da fasalulluka na kariya gami da iyakancewa ta sake zagayowar yanzu, shigar da kullewar ƙarancin ƙarfin lantarki (UVLO), kariyar wuce gona da iri (OVP), da kashe wutar lantarki. Bugu da kari, LM5176 yana fasalta matsakaicin shigarwar zaɓi na zaɓi ko ƙayyadaddun fitarwa na yanzu, zaɓin yaɗa bakan don rage kololuwar EMI, da kariyar yanayin ɓoyayyiyar zaɓi na zaɓi a cikin yanayi mai dorewa.
Ƙaƙƙarfan Tsaro na Aiki - Akwai takaddun shaida don taimakawa ƙira tsarin aminci na aiki
• Mai sarrafa inductor buck-boost mai sarrafa don mataki-sama/matakin-saukar juzu'in DC/DC
• Wide VIN: 4.2 V (2.5 V tare da son zuciya) zuwa 55 V (mafi girman 60V)
• MULKI MAI SAUKI: 0.8 V zuwa 55 V
• VOUT gajeriyar kariya
• Babban inganci Buck-bust miƙa mulki
• Mitar sauyawa mai daidaitacce
• Mitar aiki tare da zaɓin zaɓi
• Haɗaɗɗen direbobin ƙofar MOSFET 2-A
• Iyakar zagaye-zagaye na yanzu da hiccup na zaɓi
Matsakaicin matsakaicin shigarwa ko fitarwa na zaɓi
• Shigar da shirin UVLO da farawa mai laushi
• Power Good da fitarwa overvoltage kariya
• Akwai a cikin HTSSOP-28 da QFN-28 fakiti
• Ƙirƙirar ƙirar al'ada ta amfani da LM5176 tare da WEBENCH Power Designer
• Kayan wutar lantarki na PC na masana'antu
• Isar da wutar lantarki na USB
