Evaluation Board AAT2863IMK-DB1 Skyworks Solutions, Inc. Demo board for AAT2863IMK-T1
The AAT2863 is a highly integrated charge pump-based lighting management unit with four linear regulators optimized for single-cell lithium-ion/polymer systems. The charge pump provides power for all LED outputs and multiple LED configurations are available. The LED control current sinks can be programmed up to 30mA each and the two AUX LED outputs can be programmed up to 60mA each. An I 2 C serial digital interface is used to enable, disable, and set the LED current to one of 32 levels. In addition the 6 LED channels, including two AUX channels, can be configured between MAIN/SUB. High power auxiliary channels' current matching is better than 5% for matched LED color and brightness. A separate PWM input allows the LED current sinks to be modulated at high frequencies as required by CABC or Dynamic backlight power saving schemes. The AAT2863 also provides four high-performance lownoise MicroPower™ low dropout (LDO) linear regulators. The regulators are enabled and their output voltages are I2C programmable. One MicroPower™ LDO has a load current rating of 300mA and three LDOs have load current ratings of 150mA. Single LDO operating current is less than 80μA, making the AAT2863 ideal for battery-operated applications. The AAT2863 is available in a Pb-free, space-saving TQFN34-24 package and operates over the -40°C to 85°C ambient temperature range.
