♠Madalaivala a High-Voltage HB LED okhala ndi Integrated High-Side Current Sense
Ma MAX16833, MAX16833B, MAX16833C, MAX16833D, ndi MAX16833G ndi madalaivala apamwamba kwambiri a LED omwe amawongoleredwa ndi ma boost, buck-boost, SEPIC, flyback, ndi topologies zam'mbali zazitali. Dalaivala wa dimming wopangidwa kuti aziyendetsa p-channel yakunja motsatizana ndi chingwe cha LED pro vides dimming control yamitundumitundu. Izi zimapereka ma PWM othamanga kwambiri pakalipano osinthira ku ma LED opanda kupitilira kwanthawi kochepa kapena kutsika kwamagetsi. Kuphatikiza pa dimming ya PWM, ma IC amapereka dimming ya analogi pogwiritsa ntchito kulowetsa kwa DC ku ICTRL. Ma IC amamva kuwala kwa LED kumbali yakumtunda kwa chingwe cha LED.
Chotsutsa chimodzi kuchokera ku RT/SYNC kupita pansi chimayika ma frequency osinthika kuchokera ku 100kHz kupita ku 1MHz, pomwe chizindikiro cha wotchi yakunja yolumikizidwa bwino ndi RT/SYNC imalola ma ICs kulumikizana ndi wotchi yakunja. Mu MAX16833/C/G, ma frequency osinthira amatha kusinthidwa kuti agwiritse ntchito mawonekedwe ofalikira. MAX16833B/D m'malo mwake imapereka voteji ya 1.64V yokhala ndi kulolerana kwa 2%.
Ma ICs amagwira ntchito pamitundu yambiri ya 5V-to-65V ndipo amaphatikiza 3A sink/source gate driver poyendetsa MOSFET yamphamvu pama driver amphamvu kwambiri a LED. Zina zowonjezera ndi monga fault-indicator output (FLT) ya nyengo yaifupi kapena yotentha kwambiri komanso overvolt age-protection sense input (OVP) pofuna kuteteza kupitirira mphamvu. Zomverera zapambali zam'mbali zophatikizidwa ndi p-channel dimming MOSFET zimalola kuti cholumikizira chabwino cha chingwe cha LED chifupikitsidwe kupita kolowera kolowera kapena kumalo olowera opanda cholakwika popanda kuwonongeka kulikonse. Ichi ndi mawonekedwe apadera a ICs.
