PRODUCT SUMMARY  
AAT2430B  
16 Channel White LED Driver Solution with LED Current andTiming Control  
General Description  
Features  
•
•
The AAT2430B is a highly integrated, high efficiency white  
LED backlight solution for large size LCD panels used in  
LCD TVs. By controlling external power MOSFETs (such as  
the Skyworks' AAT2491 high-voltage TrenchDMOS  
array), the AAT2430B facilitates 16 current sink channels  
to provide precision constant-current drive for strings of  
white LEDs, where the number of series-connected LEDs  
per string is only limited by the system LED voltage sup-  
ply. Current in each backlight string and string-to-string  
matching is controlled using I-Precise™ sensing and con-  
trol circuitry, a novel on-chip method to accurately control  
drain current in external discrete power MOSFETs inde-  
pendent of their construction and without the need for  
precision sense resistors.  
VIN Range: 10.8V – 28V  
16 Programmable LED Current Sinks  
±1.5% Accuracy @ RSET = 3.01kΩ  
±1.5% Matching @ RSET = 3.01kΩ

VSYNC PWM and Delay Synchronization  
Device Addressing  
A 15MHz SPI compatible interface allows fast, indepen-  
dent digital control of each current sink. Full scale LED  
current is programmed using an external resistor. DOT  
correction may be applied globally to all sink channels  
with 8-bit resolution. Both phase delay and grayscale  
clock (GS Clock) PWM on-time are user programmable  
with 12-bit resolution for each current sink channel.  
Timing and synchronization are determined by exter-  
nally applied VSYNC and GS Clock signals.  
4 Possible Address Settings  
Up to 64 Current Sinks

The AAT2430B provides latched fault handling and fault  
reporting through the SPI interface and fault flag output  
pin. The fault detection system reports open or short cir-  
cuit LED strings and over-temperature events. The short  
circuit LED detection threshold is user programmable.  
Applications  
•
•
Large Size LCD TVs, Panels  
White LED Backlight, Dynamic Edge LCD TV Backlight  
The LED string supply voltage may be regulated by using  
the voltage or current mode current sense feedback sig-  
nal to the LED voltage regulator. This analog signal rep-  
resents the highest VF string of LEDs. Thermal protection  
circuitry shuts down the device in the event of an over-  
temperature condition.  
The AAT2430B is available in the Pb-free, thermally  
enhanced 64-pin 9mm x 9mm QFN and 64-pin 14mm x  
14mm LQFP packages.
