New AnalogicTech LED Backlight Drivers with CABC Save Power and Smooth Brightness Transitions in Handheld Devices
Advanced Analogic Technologies, Inc. today introduced the AAT2868 and AAT2869 LED backlight drivers. The AAT2868 and AAT2869 are 1x/1.5x dual-mode, high-efficiency charge pump based white LED backlight drivers that drive four constant current LED channels and now offer content adaptive brightness control (CABC) or dynamic backlight control (DBC) to further reduce power consumption by up to 50 percent. To form a complete lighting solution, both de...
Serial LED Driver with Filtered PWM and 32 Step S²C Dimming Control
The AAT1401, AAT1402, AAT1403 and AAT1410 are step-up single channel LED driver with an input voltage range of 2.7V to 5.5V. Parts of the AAT14xx family can drive up to 10 LEDs in a single string. 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 tha...
LED driver provides 20% lower dropout voltage, extending battery life for low cost mobile products
AnalogicTech has introduced the AHK3292, a two-channel LED driver for LED indicators and LCD or keyboard backlighting in entry-level mobile products. Featuring low resistance current sinks capable of supporting a low dropout voltage, the LED driver reduces power dissipation and extends battery life. The device’s dropout voltage of 36mV typical is at least 20% lower than competitive products.
White LED driver simplifies large display design for portable electronics
AnalogicTech has introduced the AAT1239-1, a high frequency, high efficiency constant current boost converter capable of driving up to10 white LEDs (WLEDs) connected in series. Designed for backlight applications in PNDs, eDictionaries, electronic photo frames and cellular handsets, the new driver IC uses AnalogicTech’s proprietary Simple Serial Control (S2CWire) single-wire interface to dramatically reduce the display flicker that occurs with...
