LM3648YFFR TI LED Driver | 12-DSBGA | 1.5A Flash, I2C

Product Overview

The LM3648YFFR is a high-power, dual-channel LED flash driver from Texas Instruments, designed for camera flash and torch applications in mobile devices. It integrates an inductive boost converter with two 1.5A current sinks, providing up to 3A total flash current. The device supports I2C-compatible interface for flexible control and offers programmable flash timeout, torch current, and strobe mode. Packaged in a compact 12-DSBGA (1.6mm x 1.2mm), it is ideal for space-constrained designs.
