Press Release Summary:
Designed for parallel connected LEDs, AS1101 features analog and PWM brightness control. It can drive 2 LEDs with up to 80 mA per LED, and shutdown control results in supply current drop to under 1 µA. Designed for voltage drop of less than 150 mV, driver is suited to connect directly to Li-Ion batteries without dc/dc converter. LED current is programmable using external resistor, and IC can drive any color LED for backlighting of small displays.

austriamicrosystems Introduces High-Current LED Driver
AS1101 LED driver is ideal for lighting control on mobile phones, PDAs and other portable devices
RALEIGH, N.C. (June 27, 2005) - Offering portable electronics designers a new series of high efficiency LED drivers, austriamicrosystems is introducing the AS1101 Low-Dropout LED driver for parallel connected LEDs. With analog and PWM (pulse-width modulation) brightness control, the AS1101 can drive two high-current LEDs with up to 80mA per LED - making it ideal for applications that require higher current. Additionally, the AS1101 features enable shutdown control with the supply current dropping to less than 1µA.
The Low-Dropout LED driver is designed for an ultra-low voltage drop of less than 150mV and is ideally suited to connect directly to Li-Ion batteries. No DC/DC converter is required, thus eliminating switching noise. For maximum ease of use the LED current is programmable using an external resistor.
The ability to drive any color LED, including white and blue, makes this IC ideally suited for backlighting of small displays, as well as lighting management for battery powered audio devices such as MP3 and CD players, mobile and cordless phones, PDAs, portable DVD players and consumer electronics that require high-efficiency lighting control for LED backlighting.
The AS1101 is available in an SC70-6 package and is pin-to-pin compatible to the FAN5614 from Fairchild Semiconductor. For product-specific information and to request samples please go to austriamicrosystems.com/03products/13_interfaces.htm.
