LM2794TL/NOPB TI LED Driver | 14-DSBGA | 1.5MHz, 8-Channel

Product Overview

The LM2794TL/NOPB from Texas Instruments is a high-efficiency, 8-channel LED driver designed for portable display backlighting and general-purpose lighting applications. Housed in a compact 14-DSBGA package, it integrates a 1.5MHz fixed-frequency step-up DC-DC converter with current sinks for driving up to 8 LEDs in parallel. The device operates from a single Li-Ion cell input (2.7V to 5.5V) and delivers up to 30mA per channel with excellent current matching (±1%). Its low quiescent current (0.5µA in shutdown) and high efficiency (up to 85%) make it ideal for battery-powered devices.
