AAT3113, AAT3114/14A  
High Efficiency 1.5X Fractional Charge  
Pumps For White LED Applications  
™
ChargePump  
General Description  
Features  
The AAT3113 and AAT3114/14A are low noise, con-  
stant frequency charge pump DC/DC converters  
that use fractional (1.5X) conversion to increase effi-  
ciency 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 exter-  
nal parts count (two 1µF flying capacitors and two  
small bypass capacitors at VIN and OUT) makes  
these devices ideally suited for small, battery-pow-  
ered applications.

AnalogicTech’s 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 AAT3114/14A  
devices have a thermal management 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  
disconnects the load from VIN and reduces quies-  
cent current to less than 1µA. The AAT3113 pro-  
vides four LED current source outputs, and the  
AAT3114/14A provides six. The AAT3113 is avail-  
able in a Pb-free 12-pin TSOPJW package, and the  
AAT3114/14A is available in a Pb-free 16-pin QFN  
package.
