TLD60982ESXUMA2

Overview

The TLD60982ESXUMA2 is a dual-channel multitopology DC-DC controller from the Infineon LITIX Power family, designed for automotive LED applications. It supports Boost, Buck, SEPIC, and Flyback topologies without an SPI interface to reduce system costs. The device operates with an input voltage range of 4.5 V to 58 V and delivers up to 1 A per channel, with a maximum output voltage of 70 V. It features a flexible switching frequency range from 100 kHz to 2200 kHz and includes short-circuit detection, open-load detection, and PWM dimming capabilities. Operating temperatures span from -40 °C to 150 °C.

Feature Summary

• Multitopology support including Boost, Buck, SEPIC, and Flyback configurations
• Dual independent channels with peak current control loop regulation
• Integrated diagnostic features such as short-circuit and open-load detection
• Supports PWM dimming for precise LED brightness control

Applications

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

Procurement Notes

Verify the specific suffix XUMA2 against the latest official datasheet to confirm package type and tape/reel specifications. Confirm component status, as some variants may be marked as Not Recommended for New Designs (NRND). Ensure compatibility with required thermal management for the PG-TSDSO-24 package in high-temperature automotive environments.

Selection Notes

Select this component when a cost-effective solution without SPI communication is required for complex LED topologies. It is suitable for designs needing independent channel regulation with high input voltage tolerance. Consider the absence of digital interfaces if system complexity must be minimized compared to LITIX Basic+ or Flex families.

Part Context

Part of the LITIX Power family, which focuses on basic feature requirements to minimize system costs. Unlike other LITIX series, these devices lack SPI interfaces, making them ideal for simpler control architectures. The family includes buck converters, low-side switches, and various DC-DC controllers tailored for robust automotive lighting applications.

Replacement Considerations

Check for TLD60981EPXUMA2 for single-channel applications in PG-TSDSO-14 packages. Verify if TLD6098-1EP or TLD6098-2ES generic designations apply to legacy revisions. Consult official substitution lists for any updated pin-compatible alternatives within the LITIX Power portfolio.
