LM3528TMX/NOPB TI LED Driver | 12-DSBGA | 2.7V-5.5V, 1.3A Switch

Product Overview

The LM3528TMX/NOPB is a high-efficiency, step-up DC-DC converter from Texas Instruments, designed to drive up to 10 series white LEDs for backlighting applications. It operates from an input voltage range of 2.7V to 5.5V, making it suitable for single-cell Li-Ion or Li-Polymer battery-powered devices. The device integrates a 1.3A, 0.3Ω internal switch and uses a fixed-frequency, current-mode PWM architecture for excellent line and load regulation. The LM3528TMX/NOPB is available in a compact 12-bump DSBGA package (12-DSBGA), ideal for space-constrained designs.
