Overview
The TLD5097EPXUMA1 is an automotive-grade LED boost controller from Infineon's LITIX Power family. It operates with a supply voltage range of 5.5 V to 40 V and delivers a maximum output current of 90 mA. The device integrates a switching frequency of approximately 500 kHz and supports both analog and PWM dimming methods. Designed for high reliability, it functions within a junction temperature range of -40°C to +150°C and holds AEC-Q100 qualification.
Feature Summary
- Integrated DC/DC boost controller topology optimized for LED driving applications
- Supports flexible dimming control via analog signals and pulse-width modulation inputs
- Includes built-in diagnosis and protection features for enhanced system safety
Applications
- Automotive exterior lighting systems
- LED headlamp modules
- High-intensity discharge lamp replacement circuits
Procurement Notes
Verify the specific suffix XUMA1 indicates tape-and-reel packaging when ordering. Confirm that the component meets AEC-Q100 automotive grade requirements for your target application environment. Ensure input voltage specifications align with the 5.5 V to 40 V operational range defined in the official datasheet.
Selection Notes
Select this component for designs requiring a dedicated boost controller rather than a complete driver IC. It is suitable for applications needing precise current regulation up to 90 mA with integrated fault management. Consider the PG-TSDSO package size for PCB layout constraints and verify thermal performance within the specified operating temperature limits.
Part Context
This part belongs to the LITIX Power series, which focuses on robust power management for automotive lighting. Unlike linear drivers, this controller manages energy conversion efficiently. It complements other LITIX devices by providing specialized boost functionality for high-voltage LED strings in demanding vehicle environments.
Replacement Considerations
Direct substitutes are not explicitly listed in the provided documentation. Engineers should evaluate other LITIX Power boost controllers or comparable automotive-grade LED drivers from Infineon based on pin compatibility and electrical specifications.
