TLD60981EPXUMA2

Overview

The TLD60981EPXUMA2 is a single-channel multitopology DC-DC controller from Infineon’s LITIX™ Power family, designed for automotive LED lighting. It supports flyback, SEPIC, buck, and boost topologies without internal switches. The device regulates output current via a peak current control loop with PWM dimming capability. Operating supply voltage ranges from 4.5V to 58V, while the output voltage spans 0V to 70V. The switching frequency is adjustable between 100kHz and 500kHz. It features AEC-Q100 qualification and operates within a junction temperature range of -40°C to 150°C in a PG-TSDSO-14 package.

Feature Summary

• Multitopology support including flyback, SEPIC, buck, and boost configurations for flexible power stage design
• Peak current control loop for precise LED current regulation
• PWM dimming interface for brightness control
• Automotive-grade reliability with AEC-Q100 certification

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 against the manufacturer's official datasheet to ensure correct packaging and tape-and-reel specifications. Confirm that the component meets the required AEC-Q100 grade for your target application. Check for any recent lifecycle status updates or recommended new design alternatives if the part is nearing end-of-life. Ensure compatibility with your PCB footprint for the PG-TSDSO-14 package.

Selection Notes

Select this controller when a single-channel solution supporting multiple converter topologies is required to reduce system costs. It is suitable for applications where an SPI interface is unnecessary, leveraging fixed current/voltage configuration options. Consider its wide input voltage range and high operating temperature rating for harsh automotive environments. Evaluate the need for external switch components as the device contains no internal switches.

Part Context

This component belongs to the LITIX™ Power family, which includes buck converters, low-side switch controllers, and 4-switch buck-boost controllers. Unlike other families in the lineup, LITIX™ Power devices do not feature an SPI interface, making them ideal for basic feature requirements aimed at cost reduction. The family targets automotive lighting applications with various output current capabilities.

Replacement Considerations

Consult the official LITIX™ Power comparison table for potential substitutes such as the TLD6098-1ES or TLD6098-2ES. Verify pinout compatibility and electrical parameter alignment before substitution. Ensure the alternative part maintains the required multitopology support and automotive qualification standards.
