Overview
The TLD5098EPXUMA1 is a DC/DC boost controller from the LITIX™ Power series, designed for automotive LED lighting applications. It operates with an input voltage range of 6 V to 45 V and provides an adjustable output voltage range of 4.5 V to 40 V. The device supports a maximum output current of 350 mA and delivers up to 12 W of output power in specific configurations. It utilizes a Boost topology and is qualified to Automotive quality standards.
Feature Summary
- Integrated diagnosis and protection features specifically designed for driving LEDs
- Flexible DC/DC boost controller architecture suitable for various automotive lighting topologies
- Automotive-grade qualification ensuring reliability in harsh environments
Applications
- Automotive daytime running lights
- Pre-regulator for rear LED lamps
- Constant voltage output stages in automotive lighting systems
Procurement Notes
Verify the exact suffix XUMA1 corresponds to the reel packaging configuration when ordering. Confirm that the PG-TSDSO-14 package matches your PCB footprint requirements. Ensure the design accounts for the specified input voltage range of 6 V to 45 V to maintain proper controller operation under all vehicle electrical conditions.
Selection Notes
Select this component when a robust boost controller with integrated diagnostic capabilities is required for automotive LED drivers. It is suitable for designs needing high efficiency and fault protection. Consider the 350 mA current limit and 12 W power capability against load requirements. Evaluate thermal management needs given the automotive operating temperature range and power dissipation characteristics.
Part Context
This part belongs to Infineon's LITIX™ Power family, which focuses on flexible DC/DC controllers for high-performance automotive lighting. Unlike linear drivers, this boost controller offers higher efficiency for step-up applications. It complements other LITIX devices by providing specialized topology control rather than simple current sourcing.
Replacement Considerations
Direct substitutes within the same family include variants like TLD5098EL, though pinout and specific electrical parameters must be verified against the datasheet. Cross-family replacements require careful evaluation of topology compatibility and diagnostic feature alignment.
