Evaluation Board AAT1401IUQ-DB1 Skyworks Solutions, Inc. Demo board for AAT1401IUQ-T1
The AAT1401 is a step-up single channel LED driver with an input voltage range of 2.7V to 5.5V. The wide input voltage range, small solution size, advanced dimming features and high efficiency is suitable for LED backlight solutions for single cell Li-ion based equipment. A precision, high voltage current sink maintains the maximum LED current set by an external resistor from 10 to 31mA. The high switching frequency supports ultra small, low cost filtering components. Two dimming controls are available; 32 dimming steps using the S²Cwire™ interface, and filtered PWM control. The frequency range of the PWM dimming extends up to 100 kHz eliminating audible noise and suitable for CABC (Content Adaptive Brightness Control) applications. The device includes over-temperature protection and programmable over-voltage protection and recovers automatically when the faults are removed. The AAT1401 is available in a 10-pin wafer-level chip scale package (WLCSP) and is rated over the -40°C to +85°C temperature range.
