DATA SHEET
Serial LED Driver with Filtered PWM and 32-Step S2C Dimming Control
General Description
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 ponents.
Two dimming controls are available; 32 dimming steps using the S2Cwire™ interface, and filtered PWM control. The...
