DATA SHEET  
AHK3296  
Six-Channel 1x Low Dropout LED Driver  
General Description  
Features  
The AHK3296 is a linear current-sink LED driver, capable  
of driving up to six LEDs at 20.6mA each. Featuring indi-  
vidual low resistance, low drop-out voltage current sinks,  
the AHK3296 allows the LEDs to be regulated directly  
from a Lithium Ion/Polymer battery without the need for  
an additional step-up power supply, thereby reducing the  
external component count, eliminating switching noise  
and maximizing efficiency.  
2.7V to 5.5V Input Supply Range  
Drives up to 6 LEDs at up to 20.6mA each  
Low-Drop Out, Low Resistance Current Sinks  
Typically 40.5mV at Full Scale  
Linear LED Output Current Control  
S2Cwire Interface  
Single-wire  
32 Steps  
Independent LED Current Control for Main and Sub  
Group  
±10% LED Output Current Accuracy  
±3% LED Output Current Matching  
Low Current Shutdown Mode  
Two Package Options:  
Skyworks Simple Serial Control™ (S2Cwire™) interface is  
used to enable, disable, and set the LED drive current for  
32-level linear scale LED brightness control. To minimize  
the use of external components the LED current is set  
internally to a maximum of 20.6mA.  
The AHK3296 is packaged in a Pb-free, 10-pin SC70JW  
or 10-pin TDFN2x2.2 package and operates over the  
-40°C to +85°C temperature range.
