TLD55012QVXUMA1

Overview

The TLD55012QVXUMA1 is a dual-channel LED lighting driver IC from Infineon Technologies, part of the LITIX Power Flex family. It functions as a synchronous buck DC/DC controller with an input voltage range of 4.5 V to 40 V and supports Boost, Buck-Boost, and SEPIC topologies. The device provides two output channels with a maximum output current of 90 mA per channel. It is housed in a VQFN-48 package and is AEC-Q100 qualified for automotive applications. Operating temperatures range from -40°C to +150°C.

Feature Summary

• Dual-channel architecture supporting multiple DC-DC converter topologies including Buck, Boost, Buck-Boost, and SEPIC.
• Integrated analog and PWM dimming capabilities for precise LED brightness control.
• High efficiency operation designed to minimize power loss and thermal management requirements.
• Low electromagnetic interference (EMI) emissions suitable for sensitive automotive environments.

Applications

• Automotive exterior lighting systems
• Interior vehicle illumination circuits
• LED headlight modules
• Adaptive driving beam systems

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix XUMA1 indicates the correct reel packaging configuration. Ensure compatibility with your system's thermal design given the high operating temperature rating. Check for moisture sensitivity handling requirements during storage and assembly processes.

Selection Notes

Select this component when designing automotive LED drivers requiring flexible topology support beyond simple buck conversion. The dual-channel capability allows independent control of separate LED strings. Consider the VQFN-48 package size constraints and thermal dissipation needs. Verify that the 90 mA output current meets the specific LED array requirements of the target application.

Part Context

This device belongs to the TLD5501 series within Infineon's LITIX Power Flex portfolio. These drivers are engineered specifically for robust automotive lighting applications. The series emphasizes high integration and reliability under harsh environmental conditions.
