LP8556SQ-E09/NOPB TI LED Driver | 24-WQFN (4x4) | 6-Channel, Boost Converter

Product Overview

The LP8556SQ-E09/NOPB is a high-efficiency, 6-channel LED driver from Texas Instruments, designed for backlighting applications in automotive and industrial displays. It integrates a boost converter with adaptive voltage control to maintain high efficiency across a wide LED current range. The device operates from an input voltage of 2.7V to 20V and can drive up to 6 strings of LEDs with programmable current up to 30mA per channel. The LP8556 features PWM dimming with a 10-bit resolution, phase-shifted PWM for reduced audible noise, and comprehensive fault protection including LED open/short detection, overvoltage, and overtemperature protection. Housed in a compact 24-WQFN (4x4 mm) package, it is ideal for space-constrained applications.
