♠Amashayeli e-LED e-High-Voltage HB ane-Integrated High-Side Current Sense
I-MAX16833, MAX16833B, MAX16833C, MAX16833D, kanye ne-MAX16833G amashayeli e-LED alawulwa yimodi yamanje ephakeme kakhulu, i-buck-boost, i-SEPIC, i-flyback, kanye ne-toplogies yebhali eseceleni ephezulu. Umshayeli wokufiphalisa odizayinelwe ukushayela i-p-channel yangaphandle ngochungechunge ngeyunithi yezinhlamvu ze-LED pro vides control-range dimming control. Lesi sici sihlinzeka ngokushintsha kwamanje kwe-PWM eshesha kakhulu ukuya kuma-LED angenakho ukuguquguquka kwesikhashana noma izimo ezingaphansi kwamandla. Ngokungeziwe ekufiphaleni kwe-PWM, ama-IC ahlinzeka ngokufiphala kwe-analog kusetshenziswa okokufaka kwe-DC ku-ICTRL. Ama-ICs ezwa i-LED yamanje ohlangothini oluphezulu lwentambo ye-LED.
Isivimbeli esisodwa esisuka ku-RT/SYNC siye phansi sisetha imvamisa yokushintsha isuka ku-100kHz iye ku-1MHz, kuyilapho isignali yewashi yangaphandle ehlanganiswe ngokunamandla ne-RT/SYNC ivumela ama-ICs ukuthi avumelanise iwashi langaphandle. Ku-MAX16833/C/G, imvamisa yokushintsha ingafakwa kuhlelo lokusebenza lwe-spread-spectrum. I-MAX16833B/D esikhundleni salokho ihlinzeka nge-voltage eyireferensi engu-1.64V enokubekezelela okungu-2%.
Ama-IC asebenza ebangeni elibanzi lokuhlinzeka nge-5V-to-65V futhi afaka umshayeli wesango lokucwilisa ongu-3A/umthombo wokushayela i-MOSFET yamandla ezinhlelweni zokushayela ze-LED zamandla aphezulu. Izici ezengeziwe zifaka i-fault-indicator output (FLT) yezimo ezimfushane noma ezishisa kakhulu kanye ne-overvolt age-protection sense input (OVP) yokuvikela ukugcwala ngokweqile. Inzwa yamanje yohlangothi oluphezulu ehlanganiswe ne-p-channel dimming MOSFET ivumela itheminali ephozithivu yeyunithi yezinhlamvu ye-LED ukuthi ifinyezwe kutheminali yokufaka ephozithivu noma kutheminali yokokufaka okunegethivu ngaphandle kokulimala. Lesi isici esiyingqayizivele sama-IC.
