TLD6098-1EP

Overview

The TLD6098-1EP is a single-channel multitopology DC-DC controller from Infineon’s LITIX™ Power family, designed for automotive LED lighting applications. It supports Boost, Buck, SEPIC, and Flyback topologies with an input voltage range of 4.5 V to 60 V and output voltages up to 70 V. The device operates at switching frequencies between 100 kHz and 2200 kHz, delivering up to 3 A output current via an external N-channel MOSFET. It features PWM dimming, integrated diagnostics, and protection mechanisms including short-circuit detection and open-load detection, ensuring compliance with automotive standards.

Feature Summary

• Multitopology support enabling flexible circuit designs for various LED driving requirements
• Integrated diagnostic and protection functions for enhanced system reliability
• PWM dimming capability with reduced color shift for high-quality lighting control

Applications

• Automotive LED front single light functions
• Full LED headlight systems
• LED driver solutions for electric two- and three-wheelers

Procurement Notes

Verify the specific ordering suffix (e.g., XUMA2 or XUMA3) to confirm package type and reel configuration. Ensure compatibility with your PCB footprint, as the component uses a PG-TSDSO-14 package. Cross-reference the datasheet revision date to guarantee access to the latest electrical characteristics and application notes before finalizing procurement.

Selection Notes

Select this controller when designing circuits requiring multiple topologies such as Boost, Buck, or SEPIC within a single channel. It is suitable for applications needing wide input voltage ranges and integrated fault diagnosis. Consider the external MOSFET requirement and thermal management needs based on the target output power and switching frequency settings.

Part Context

Part of the LITIX™ Power series, the TLD6098-1EP targets robust automotive lighting systems. It complements evaluation boards like the TLD609812BEVALTOBO1 for Boost topology testing. The device integrates seamlessly into complex lighting architectures, offering a balance of performance, diagnostic depth, and flexibility for modern vehicle illumination designs.

Replacement Considerations

Check for updated XUMA3 variants which may offer minor packaging or tape-and-reel differences. No direct functional pin-to-pin replacements are explicitly documented in public sources; verify electrical equivalence carefully if considering alternative manufacturers.
