MAX8847/48: Backlight drivers with adaptive mode switching boost efficiency by 12% in portable devices
Maxim Integrated Products introduces the MAX8847/MAX8848, negative charge pumps for up to 6 or 7 white LEDs (WLEDs) in a 3mm x 3mm TQFN package. These backlight drivers employ a negative-charge-pump architecture to eliminate in-line resistance from the battery to WLEDs. As a result, mode switching from 1x to 1.5x is delayed during battery discharge, thereby minimizing dropout. The proprietary adaptive-mode-switching technology controls each LED i...
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...
