TLD5085EJFUMA1

Overview

The TLD5085EJFUMA1 is a single-channel LED driver IC from Infineon’s LITIX™ series, designed for automotive backlighting applications. It integrates a step-down (buck) DC/DC converter with an internal switch, supporting PWM dimming. The device operates within a supply voltage range of 4.75V to 45V and delivers an output current of 1.8A per channel. The regulated output voltage spans from 0.6V to 16V at a switching frequency of 370kHz. It functions reliably across a junction temperature range of -40°C to 150°C and is housed in an 8-DSO package.

Feature Summary

• Integrates a high-efficiency buck converter topology with an internal power switch for compact design
• Supports precise digital control via PWM dimming interface for adaptive lighting systems
• Includes comprehensive protection mechanisms such as overload, short circuit, and over-temperature safeguards

Applications

• Automotive interior and exterior LED backlighting
• High-brightness LED driving in vehicle lighting modules
• General-purpose low-voltage LED regulation in automotive environments

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix 'FUMA1' matches the required packaging and tape-and-reel specifications. Check for obsolescence status, as this part may be discontinued. Ensure compatibility with existing PCB footprints for the PG-DSO-8 package before finalizing procurement orders.

Selection Notes

Select this component when a single-channel, high-current LED driver with integrated buck conversion is required. It is suitable for designs needing robust automotive-grade reliability and wide input voltage tolerance. Consider alternative parts if multiple independent channels or different topologies like boost are necessary for the specific application architecture.

Part Context

This device belongs to Infineon’s LITIX™ family, specialized for intelligent power management in automotive lighting. It addresses the need for efficient, reliable LED control in harsh environmental conditions. The integration of the driver and converter reduces external component count, simplifying layout and improving system stability compared to discrete solutions.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify functional equivalence carefully if considering alternatives from other manufacturers, ensuring matching electrical parameters and package dimensions.
