Overview
The TPS75103YFFT is a Texas Instruments LED lighting driver IC featuring a low-dropout linear regulator with two independent output banks. It supports PWM brightness control and operates within an input voltage range of 2.7 V to 5.5 V. The device provides four constant current outputs, each capable of delivering up to 25 mA. Packaged in a compact DSBGA-9 format, it functions across a temperature range of -40°C to +85°C. Key electrical parameters include a maximum quiescent current of 300 µA and thermal shutdown protection for enhanced reliability.
Feature Summary
- Integrates two independent LED driver banks with four constant current channels
- Supports precise PWM dimming for adjustable brightness control
- Includes built-in thermal shutdown protection for safe operation
- Features enable/shutdown functionality for power management
Applications
- LED backlighting systems

- Portable electronic display drivers
Procurement Notes
Verify the specific suffix 'YFFT' corresponds to the tape-and-reel packaging configuration required for your assembly process. Confirm that the component status remains active with Texas Instruments before finalizing procurement plans. Ensure compatibility with standard SMD/SMT mounting techniques suitable for the DSBGA-9 package dimensions.
Selection Notes
Select this component when designing circuits requiring dual-bank LED control with integrated linear regulation. It is suitable for applications needing PWM dimming capabilities without external complex driver stages. Consider the 25 mA per channel limit and the 2.7 V to 5.5 V input range to ensure proper headroom and efficiency for your specific LED load requirements.
Part Context
This part belongs to the TPS7510x series of low-dropout LED drivers from Texas Instruments. These devices are designed specifically for driving LEDs in portable and general lighting applications. The series offers a balance of performance and simplicity by integrating regulation and control features into a small footprint, reducing the need for external components compared to discrete solutions.
