♠High-Voltage HB LED Drivers with Integrated High-Side Current Sense
MAX16833, MAX16833B, MAX16833C, MAX16833D, le MAX16833G ke li-driver tsa LED tse laoloang hona joale bakeng sa boost, buck-boost, SEPIC, flyback, le li-topology tsa mahlakoreng a holimo. Mokhanni oa dimming o etselitsoeng ho khanna p-channel ea kantle ka letoto le nang le thapo ea LED e fana ka taolo e pharalletseng ea ho fifala. Karolo ena e fana ka phetoho ea hona joale ea PWM e potlakileng haholo ho li-LED ntle le ho fetella kapa maemo a undervoltage. Ntle le ho fifala ha PWM, li-IC li fana ka dimming ea analog ho sebelisa kenyelletso ea DC ho ICTRL. Li-IC li utloa khanya ea LED ka lehlakoreng le phahameng la khoele ea LED.
Mohanyetsi o le mong ho tloha RT/SYNC ho ea fatše o beha maqhubu a ho fetoha ho tloha 100kHz ho isa 1MHz, ha lets'oao la oache la kantle le kopantsoeng hantle le RT/SYNC le lumella li-IC hore li hokahane le oache e kantle. Ho MAX16833/C/G, maqhubu a switjha a ka fokotsoa bakeng sa lits'ebetso tsa marang-rang. MAX16833B/D ho fapana le moo e fana ka voltage ea referense ea 1.64V e nang le mamello ea 2%.
Li-IC li sebetsa holim'a mefuta e mengata ea phepelo ea 5V-to-65V 'me e kenyelletsa 3A sink / mokhanni oa heke ea mohloli bakeng sa ho khanna MOSFET ea matla lits'ebetsong tsa mokhanni oa LED oa matla a phahameng. Likarolo tse ling li kenyelletsa sephetho sa fault-indicator output (FLT) bakeng sa maemo a mokhuts'oane kapa mocheso o feteletseng le "overvolt age-protection sense input" (OVP) bakeng sa tshireletso ya overvoltage. Kutlo ea hona joale ea mahlakoreng a holimo e kopantsoeng le p-channel dimming MOSFET e lumella theminale e ntle ea thapo ea LED hore e khutsufatsoe ho terminal ea ho kenya e positive kapa ho terminal e kenang e fosahetseng ntle le tšenyo ea letho. Ena ke tšobotsi e ikhethang ea li-IC.
