The MAX1698EUB from Maxim Integrated is an efficient switch-mode boost controller designed as a step-up current regulator for LEDs. It is particularly suited for large LED backlit displays found in PDAs and laptop computers, offering greater simplicity, lower cost, higher efficiency, and longer bulb life compared to traditional fluorescent or electroluminescent lamps.
This device regulates LED current directly, measured using a typical 15 Ω sense resistor. LED current control and dimming are managed via an adjust input (ADJ). It supports parallel connection of multiple LED banks for higher light output, with a total output power capability of up to 5W. The MAX1698A variant offers a higher, more accurately specified CS current limit for applications requiring 5W or more.
The MAX1698EUB is supplied in a space-saving 10-pin µMAX package. An evaluation kit, MAX1698EVKIT, is available to facilitate design processes. Key features include over 90% efficiency, lossless adjustable LED brightness, and a simpler, more reliable design compared to CCFL or EL backlights.
The MAX1698EUB can deliver up to 5W output power.
The efficiency is greater than 90%.
The sense resistor value is 15Ω.
The MAX1698EUB is available in U10-2 and 10-uMAX surface-mount packages.
