LP8556SQE-E09/NOPB TI LED Driver | 24-WQFN (4x4) | 6-Channel, Boost, PWM Dimming

Product Overview

The LP8556SQE-E09/NOPB is a high-efficiency, 6-channel white LED driver from Texas Instruments, designed for large-size LCD panel backlighting. It integrates a boost converter with programmable output voltage up to 40V, and each channel can drive up to 10 LEDs in series. The device features PWM dimming with a frequency range of 100Hz to 30kHz, and supports both analog and PWM dimming modes. Housed in a compact 24-pin WQFN (4x4mm) package, it offers excellent thermal performance and space savings for space-constrained applications.
