LP8556SQX-E00/NOPB TI LED Driver | 24-WQFN (4x4) | 6-Channel, Boost, PWM Dimming

Product Overview

The LP8556SQX-E00/NOPB is a high-efficiency, 6-channel LED driver from Texas Instruments, designed for backlighting applications in LCD displays. It integrates a boost converter with current sinks to drive up to 6 strings of LEDs in parallel, with each string capable of handling up to 30 mA. The device operates from an input voltage range of 2.7 V to 5.5 V, making it suitable for battery-powered devices. The LP8556 features PWM dimming with a frequency range of 100 Hz to 30 kHz, enabling smooth brightness control. The compact 24-WQFN (4x4 mm) package allows for space-constrained designs.
