High-Efficiency Step-Up  
Current Regulator for LEDs  
General Description  
Features  
The MAX1698 is the most efficient driver for white or  
color LEDs. The device is ideal for LED backlit displays  
in PDAs and digital cameras, and can also be used for  
larger displays like those in laptop computers. Its  
numerous benefits include greater simplicity, lower  
cost, higher efficiency, longer bulb life, and greater reli-  
ability when compared to fluorescent (CCFL) and elec-  
troluminescent (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  
ꢀ Up to 5W Output Power  
The MAX1698 is a switch-mode boost controller in  
which LED current, rather than output voltage, provides  
the feedback signal. It can operate with battery inputs  
as low as 0.8V. The device drives series-connected  
LEDs with a controlled current that is measured at a  
sense resistor connected at the feedback pin. The  
required sense resistor is typically 15Ω, not an expen-  
sive fractional-ohm value. LED current control and dim-  
ming are accomplished with an adjust input (ADJ), not  
with lossy current-limiting resistors. For larger light out-  
put, multiple LED banks can be connected in parallel  
with up to 5W total output power.
