Data Sheet  
AS1101, AS1102, AS1103, AS1104  
Low-Dropout LED Drivers  
1 General Description  
2 Key Features  
LED Drivers for Parallel-Connected LEDs  
The AS1101/AS1102/AS1103/AS1104 are LED drivers  
designed to match current source bias for any color  
LED, including white and blue. The devices can drive up  
to 4 high-current LEDs, and the LED current is program-  
mable using an external resistor (RSET).  
Ultra-Low Voltage Drop: Less Than 150mV (for Li-  
ion Battery Support)  
Analog and PWM Brightness Control  
Up to 80mA per LED (AS1101)  
The AS1101 LED currents are 460 x ISET (per LED, typ)  
at an LED cathode voltage (VSAT) of 150mV and 650 x  
ISET (typ) at a VSAT of 1V, where ISET is the current  
through RSET connected to pin CTRL.  
Up to 40mA per LED (AS1102, AS1103, AS1104)  
No Electromagnetic Interference, No Switching-  
Noise  
The AS1102, AS1103, and AS1104 LED currents are  
230 x ISET (per LED, typ) at a VSAT of 150mV and 325 x  
ISET (typ) at a VSAT of 1V.  
Current-Matching Requires No External Compo-  
nents  
Active-Low Shutdown Mode (AS1101, AS1102,  
and AS1103)  
The AS1101, AS1102, and AS1104 incorporate a chip-  
enable feature via pin ON. When the devices are dis-  
abled, the supply current drops to less than 1µA.  
Low Shutdown-Current: Less Than 1µA  
SC70-6 Package (AS1101, AS1102, and AS1103)  
MSOP-8 Package (AS1104)  
The AS1101, AS1102, and AS1103 are available in a  
6-pin SC70 package; the AS1104 is available in a 8-pin  
MSOP package.  
3 Applications  
The AS110x devices are ideal for LED displays and key-  
board backlights, as well as lighting management units  
for battery powered audio devices such as MP3 and CD  
players, mobile and cordless phones, PDAs, portable  
DVD players, and consumer electronics.
