TPS75103YFFR

Overview

The TPS75103YFFR is a low dropout, two-bank LED driver from Texas Instruments designed for white-LED applications. It operates within an input voltage range of 2.7 V to 5.5 V and supports up to four channels with a maximum output current of 25 mA per channel. The device utilizes a DSBGA-9 package and functions across a temperature range of -40°C to +85°C. Key electrical specifications include a typical dropout voltage of 28 mV and a maximum power dissipation of 704 mW.

Feature Summary

• Provides linear matched independent current sources for precise LED brightness control
• Supports PWM dimming functionality for adjustable brightness levels
• Features thermal shutdown protection to ensure operational safety
• Eliminates internal switching signals to mitigate electromagnetic interference

Applications

• White-LED backlighting systems
• Portable electronic device illumination
• Low-power LED lighting modules

Procurement Notes

Verify the specific suffix 'YFFR' against official Texas Instruments documentation to confirm reel packaging requirements. Ensure compatibility with standard surface-mount assembly processes. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and current production status before finalizing procurement orders.

Selection Notes

Select this component when designing compact LED drivers requiring low dropout voltage and minimal electromagnetic interference. It is suitable for applications needing independent current regulation for multiple LEDs without complex external circuitry. Consider the DSBGA-9 package size constraints and thermal management capabilities during the initial design phase.

Part Context

This component belongs to the TPS7510x series of low dropout LED drivers. It shares functional similarities with models like the TPS75100 and TPS75105 but differs in specific configuration options. The series is characterized by its ability to drive common-cathode LED topologies efficiently while maintaining a small solution size.

Replacement Considerations

Publicly confirmed substitute part numbers include TPS75100YFFT, TPS75103YFFT, TPS75105YFFR, and TPS75105YFFT.
