LP8552TLX/NOPB TI LED Driver | 25-USMD | 6-Channel, Boost, PWM Dimming

Product Overview

The LP8552TLX/NOPB is a high-efficiency, 6-channel white LED driver from Texas Instruments, designed for backlighting applications in medium-sized LCD displays. It integrates a boost converter with current sinks to drive up to 6 strings of LEDs in parallel, with each channel capable of sinking up to 25 mA. The device operates from a wide input voltage range of 2.7V to 5.5V, making it suitable for battery-powered devices. The LP8552TLX/NOPB features PWM dimming for precise brightness control and supports an I2C interface for flexible configuration. Housed in a compact 25-bump USMD package (2.0mm x 2.0mm), it is ideal for space-constrained designs.
