LP8552TLE-E04/NOPB TI LED Driver | 25-DSBGA | 4-Channel, 40V, PWM Dimming

Product Overview

The LP8552TLE-E04/NOPB is a high-efficiency, 4-channel LED driver from Texas Instruments, designed for backlighting applications in LCD displays. It integrates a boost converter and current sinks to drive up to 4 strings of LEDs with excellent current matching. The device operates from an input voltage range of 2.7V to 5.5V and can boost up to 40V, making it suitable for medium-sized LCD panels. The LP8552 features PWM dimming with a wide dimming ratio, programmable switching frequency, and comprehensive protection features including over-voltage, over-current, and thermal shutdown. Housed in a compact 25-bump DSBGA package (2.0mm x 2.0mm), it is ideal for space-constrained applications.
