TLD5190QUXUMA1

Overview

The TLD5190QUXUMA1 is an automotive-grade LED lighting driver IC from Infineon's LITIX Power series. It functions as a DC-DC synchronous H-bridge controller supporting both Buck and Boost topologies. The device operates within a supply voltage range of 4.5 V to 45 V, delivering up to 90 mA output current with a maximum output voltage of 55 V. It supports PWM dimming and operates at frequencies between 200 kHz and 700 kHz. Packaged in a PG-TQFP-48 format, it is qualified under AEC-Q100 standards for temperatures ranging from -40°C to +150°C.

Feature Summary

Synchronous H-Bridge DC/DC Controller
Automotive Grade Qualification
PWM Dimming Support

Applications

High power LED regulation in automotive lighting systems
Automotive exterior lighting applications
Interior automotive lighting control

Procurement Notes

Verify the specific suffix XUMA1 confirms the PG-TQFP-48 package variant when sourcing. Confirm AEC-Q100 qualification status aligns with project requirements. Check moisture sensitivity level (MSL 3) handling constraints during assembly. Ensure input voltage specifications match the target vehicle electrical system architecture.

Selection Notes

Select this component for single-channel high-power LED drivers requiring integrated H-bridge topology. Suitable for designs needing both step-up and step-down capabilities within one controller. Ideal for automotive environments demanding high thermal stability and strict reliability standards. Consider pin compatibility if replacing older LITIX variants.

Part Context

Part of the LITIX Power family designed specifically for automotive LED applications. Manufactured by Infineon Technologies, it integrates advanced power management features. The QU suffix indicates the TQFP package option, distinct from the QV QFN variant. It serves as a core controller for efficient light regulation in modern vehicle lighting architectures.
