LP8551TLX-A/NOPB TI LED Driver | 25-DSBGA | 6-Channel, Boost, PWM Dimming

Product Overview

The LP8551TLX-A/NOPB is a high-efficiency, 6-channel white LED driver from Texas Instruments, designed for backlighting applications in portable devices. It integrates a boost converter with current sinks to drive up to 6 strings of LEDs in parallel, with programmable PWM dimming for precise brightness control. The device operates from a 2.7V to 5.5V input voltage range and can boost up to 40V, making it suitable for small to medium-sized LCD panels. Housed in a compact 25-DSBGA package (2.0mm x 2.0mm), it offers a space-saving solution for slim designs.
