Austria launch large current LED drive

The world's leading industrial, medical, communications and automotive applications of integrated circuit design and manufacturer of Austria Microelectronics Corporation (austriamicrosystems) launched to support parallel LED low dropout LED driver AS1101, so as to provide a series of efficient LED drive for portable electronic designers. Through the analog and PWM (pulse width modulation) brightness control, AS1101 can drive 2 currents are up to 80mA high current LED, is the ideal choice for high current applications. In addition, when the supply current is reduced to 1 below A, AS1101 can automatically turn on / off control. Below the ultra low voltage drop of 150mV design, the low dropout LED driver can be directly connected to the lithium ion battery, do not need the DC/DC converter, so as to avoid switching noise. The highlight of this product is that it can be programmed by an external resistor LED current.

The new IC can drive the blue light and white light, colored LED backlight can effectively control a small display, but also for battery powered audio equipment to provide lighting management, such as providing efficient management of LED backlight brightness required for MP3 and CD player, mobile phone, cordless phone, PDA, portable DVD player and other consumer electronics products.

AS1101 uses SC70-6 package, pin compatible Fairchild FAN5614.
