High-Efficiency Step-Up  
Current Regulator for LEDs  
General Description  
Features  
The MAX1698 and MAX1698A are efficient drivers for  
white or color LEDs. They are ideal for large LED backlit  
displays in PDAs and laptop computers. Numerous  
benefits include greater simplicity, lower cost, higher  
efficiency, longer bulb life, and greater reliability when  
compared to fluorescent (CCFL) and electrolumines-  
cent (EL) lamps.  
♦ Over 90% Efficiency  
♦ Lossless, Adjustable LED Brightness  
♦ Space-Saving 10-Pin µMAX Package  
♦ Simpler, Lower Cost, More Reliable Compared  
to CCFL or EL Backlights  
The MAX1698/MAX1698A are switch-mode boost con-  
trollers in which LED current, rather than output voltage,  
is regulated The devices drive series-connected LEDs  
with a controlled current that is measured with a typical-  
ly 15Ω sense resistor, not an expensive fractional-ohm  
value. LED current control and dimming are accom-  
plished with an adjust input (ADJ). For larger light out-  
put, multiple LED banks can be connected in parallel  
with up to 5W total output power.  
♦ Up to 5W Output Power

The MAX1698A has a higher, and more accurately  
specified, CS current limit than the MAX1698 for higher-  
power applications of 5W or more. Both devices are  
supplied in a space-saving 10-pin µMAX package that  
occupies half the space of an 8-pin SO. An evaluation  
kit (MAX1698EVKIT) is available to speed designs.
