TPS61325YFFR

Overview

The TPS61325YFFR is a multi-output LED camera flash driver manufactured by Texas Instruments. It operates with an input voltage range of 2.5 V to 5.5 V and provides three independent output channels. The device supports high-level output currents up to 4.1 A and low-level currents of 1.5 A, suitable for driving multiple LEDs in parallel or series configurations. It features a fixed switching frequency of 1.5 MHz and includes I2C-compatible interface control for configuration. The component functions within a temperature range of -40°C to +85°C and is housed in a DSBGA-20 package.

Feature Summary

• Supports simultaneous multi-channel LED driving with independent current regulation capabilities
• Integrates an I2C-compatible serial interface for programmable control and status monitoring
• Includes load disconnect functionality during shutdown to prevent leakage currents

Applications

• Camera flash drivers for mobile devices
• Multi-LED lighting systems requiring synchronized operation
• Portable electronic devices with integrated imaging modules

Procurement Notes

Verify the specific suffix YFFR corresponds to the DSBGA-20 package variant when sourcing. Confirm that the required I2C address settings align with system bus constraints. Ensure thermal management solutions accommodate the power dissipation characteristics of the selected output configuration. Validate compatibility with the host controller's I2C voltage levels before integration.

Selection Notes

Select this component when designing circuits requiring precise control over multiple LED channels via digital interfaces. It is appropriate for applications needing high peak currents for flash illumination while maintaining efficient power usage during standby. Consider the DSBGA-20 package size constraints and the necessity for I2C communication overhead in the system architecture.

Part Context

This part belongs to the TPS61325 family of LED drivers designed specifically for camera flash applications. It distinguishes itself through multi-output capability and digital control integration, differing from single-channel boost converters. The YFFR designation identifies the specific tape-and-reel packaging format for automated assembly processes.
