AAT1236  
High Efficiency White LED Drivers  
for Backlight and Keypad  
™
SwitchReg  
General Description  
Features  
The AAT1236 is a highly integrated, high efficiency  
power solution for white LED and keypad backlights  
in mobile/portable devices. It is based on a switching  
boost converter which steps up the single cell lithi-  
um-ion/polymer battery voltage to drive 5 strings of  
series-connected white LEDs with precision current  
regulation. The AAT1236 is capable of driving a total  
of four LEDs per channel.

•
•
Input Supply Voltage Range: 2.7V to 5.5V  
Maximum Boost Output Drive: Up to 24V at 100mA  
Up to 85% Efficient Operation  
Up to 2MHz Switching Frequency with Small  
Inductor  
•
•
User-Programmable Full-Scale LED Current,  
Up to 30mA  
Two-Wire, I2C Compliant Serial Interface  
— Two Addressable Registers  
The boost converter can produce an output drive of  
up to 24V at 100mA. The high switching frequency  
(up to 2MHz) provides fast response to load tran-  
sients and allows the use of small external compo-  
nents. A fully integrated control circuit simplifies the  
design and reduces total solution size.  
•
Independent LED Current Control by Group  
— Backlight Group B1-B2, 16 Settings  
— Auxiliary Group A1-A3, 16 Settings  
Independent LED ON/OFF Control  
•
— Fast, 400kHz Serial Transfer Rate  
Non-Pulsating, High-Performance LED Current  
Drive for Uniform Illumination  
•
A two-wire I2C serial digital interface is used to indi-  
vidually turn each output sink on/off and adjust the  
LED current by group. Unlike conventional pulse  
width modulation (PWM) control of LED brightness,  
the AAT1236 drives the LEDs with constant, non-  
pulsating current. The interface is fully compliant to  
the Fast/Standard mode I2C specification, allowing a  
transfer rate of up to 400kHz.  
— 10% Absolute Accuracy  
— 2% Channel-to-Channel Matching  
Over-Voltage and Over-Temperature Protection  
Automatic Soft-Start Minimizes Large Inrush  
Current at Startup

Available in 3x4mm TDFN34-16 Package  
A similar device is also available with a proprietary  
Advanced Simple Serial Control™ (AS2Cwire™) sin-  
gle wire interface; please see the AAT1235 datasheet.
