MAX16833CAUE/V+T Direbobin Hasken Haske na LED High-Voltage HB LED Direbobi tare da Haɗin Haɗin Babban Gefe na Yanzu

MAX16833, MAX16833B, MAX16833C, MAX16833D, da MAX16833G sune manyan direbobin LED masu sarrafa yanayin halin yanzu don haɓakawa, haɓaka buck-buck, SEPIC, tashi baya, da manyan kantunan buck topologies. Direba mai raɗaɗi da aka ƙera don fitar da tashar p-tashar waje a cikin jeri tare da kirtan LED yana ba da ikon sarrafa dimming mai faɗi. Wannan fasalin yana ba da saurin jujjuyawar PWM na yanzu zuwa LEDs ba tare da wuce gona da iri ba ko yanayin rashin ƙarfi. Baya ga dimming PWM, ICs suna samar da dimming analog ta amfani da shigarwar DC a ICTRL. ICs suna jin halin yanzu na LED a babban gefen layin LED.

Mai tsayayya guda ɗaya daga RT/SYNC zuwa ƙasa yana saita mitar sauyawa daga 100kHz zuwa 1MHz, yayin da siginar agogon waje mai ƙarfi tare da RT/SYNC yana ba ICs damar daidaitawa zuwa agogon waje. A cikin MAX16833/C/G, ana iya karkatar da mitar sauyawa don aikace-aikacen bakan-bakan. MAX16833B/D a maimakon haka yana ba da wutar lantarki ta 1.64V tare da juriya 2%.

ICs suna aiki akan kewayon wadatar 5V-zuwa-65V kuma sun haɗa da 3A nutse / direban kofa don tuki MOSFET mai ƙarfi a cikin aikace-aikacen direban LED mai ƙarfi. Ƙarin fasalulluka sun haɗa da fitowar mai nuna kuskure (FLT) don gajere ko yanayin zafi fiye da kima da shigar da ma'anar kariyar shekaru fiye da kima (OVP) don kariyar wuce gona da iri. Haɓaka babban gefen halin yanzu haɗe da p-tashar dimming MOSFET yana ba da damar ingantacciyar madaidaicin igiyar LED ta gajarta zuwa ingantaccen tashar shigarwa ko zuwa tashar shigarwa mara kyau ba tare da lalacewa ba. Wannan siffa ce ta musamman na ICs.
