Low-Dropout LED Drivers

1 General Description

2 Key Features

ꢀ

LED Drivers for Parallel-Connected LEDs

The AS110x family are LED drivers providing matched

current source bias for any color LED, including white

and blue. LED current is programmable using an exter-

nal resistor.

ꢀ

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 typical 460 x ISET (per

LED) at an LED cathode voltage of 150mV and typical

650 x ISET at an LED cathode voltage of 1V.

Up to 40mA per LED (AS1102, AS1103, AS1104)

No Electromagnetic Interference, No Switching-

Noise

The AS1102, AS1103, and AS1104 LED currents are

typical 230 x ISET (per LED) at an LED cathode voltage

of 150mV and typical 325 x ISET at an LED cathode volt-

age of 1V where ISET is the current through the external

resistor connected to the CTRL pin.

ꢀ

Current-Matching Requires No External Compo-

nents

Active-Low Shutdown Mode (AS1101, AS1102,

and AS1103)

The AS110x family can drive up to 4 high-current LEDs.

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)

Pin-to-Pin Compatible to FAN5611, FAN5612, and

FAN5614

The devices are pin-to-pin compatible to the FAN5611,

FAN5612 and FAN5614.

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.
