DATA SHEET  
AAT3113/3114  
High Efficiency 1.5X Fractional Charge Pumps for White LED Applications  
General Description  
Features  
The AAT3113 and AAT3114 are low noise, constant fre-  
quency charge pump DC/DC converters that use frac-  
tional (1.5X) conversion to increase efficiency in white  
LED applications. The devices can be used to produce  
current levels up to 20mA for each output from a 2.7V  
to 5.5V input. A low external parts count (two 1μF flying  
capacitors and two small bypass capacitors at VIN and  
OUT) makes these devices ideally suited for small, bat-  
tery-powered applications.  
• AAT3113: Four Outputs  
• AAT3114: Six Outputs  
• 20mA Full-Scale Current  
• Simple Serial Control (S2Cwire) Interface  
32-Position Logarithmic Scale with Digital Control  
▪
• Low Noise Constant Frequency Operation  
• 33% Less Input Current Than Doubler Charge Pump  
• High Accuracy Brightness Matching  
• Small Application Circuit  
• Regulated Output Current  
• Automatic Soft Start  
• VIN Range: 2.7V to 5.5V  
• No Inductors  
• 600kHz Switching Frequency  
• IQ <1μA in Shutdown  
• Temperature Range: -40°C to 85°C  
• 12-Pin TSOPJW Package (AAT3113)  
• 16-Pin QFN Package (AAT3114)  
Skyworks' Simple Serial Control (S2Cwire™) interface is  
used to enable, disable, and set the LED drive current for  
32-level logarithmic scale LED brightness control.  
AAT3113 and AAT3114 devices have a thermal manage-  
ment system for protection in the event of a short-circuit  
condition on any of the output pins. Built-in soft-start  
circuitry prevents excessive inrush current during start-  
up. A high switching frequency enables the use of small  
external capacitors. A low-current shutdown feature dis-  
connects the load from VIN and reduces quiescent current  
to less than 1μA. The AAT3113 provides four LED current  
source outputs, and the AAT3114 provides six. The  
AAT3113 is available in a Pb-free 12-pin TSOPJW pack-  
age, and the AAT3114 is available in a Pb-free 16-pin  
QFN package.
