LM3631YFFR TI LED Driver | 24-DSBGA (2.59X1.89) | 4-Channel, 1.5A Total

Product Overview

The LM3631YFFR from Texas Instruments is a high-efficiency, 4-channel LED driver designed for backlighting and general illumination applications. Housed in a compact 24-DSBGA (2.59x1.89 mm) package, it integrates a boost converter with current sinks to drive up to 4 strings of LEDs. With a total output current of 1.5A and an input voltage range of 2.7V to 5.5V, it is ideal for portable devices, automotive displays, and industrial panels. The device features PWM dimming, fault protection, and I2C interface for flexible control.
