LM3644TTYFFR TI LED Driver | 12-DSBGA | Dual Flash, 1.5A

Product Overview

The LM3644TTYFFR is a high-performance dual-channel LED flash driver from Texas Instruments, designed for camera flash applications in mobile devices and compact cameras. It integrates two 1.5A current sinks with programmable current levels, enabling synchronized flash and torch modes. The device operates from a 2.5V to 5.5V input voltage range and features I2C-compatible interface for flexible control. Housed in a 12-pin DSBGA package (0.4mm pitch), it offers a compact solution for space-constrained designs.
