ZXLD1366QDACTC

Overview

The ZXLD1366QDACTC is an automotive-compliant, high-accuracy 1A LED driver with an internal switch. It operates as a continuous mode inductive step-down converter from a 6V to 60V input supply. The device provides up to 1A output current and supports PWM dimming with resolutions up to 1000:1. It features inherent open-circuit LED protection and achieves efficiencies up to 97%. The component is housed in a thermally enhanced VDFN3030-6 package.

Feature Summary

Automotive-grade reliability compliant with AEC-Q100 standards
High accuracy output current regulation typically better than 0.8%
Integrated high-side current sensing circuit for simplified design
Single-pin control for on/off switching and brightness adjustment

Applications

Automotive lighting systems
Low voltage halogen replacement LEDs
Emergency lighting circuits
Illuminated signs and displays

Procurement Notes

Verify the specific suffix 'Q' confirms AEC-Q100 automotive qualification status. Confirm the 'D' indicates the DFN-6 package variant. Ensure compatibility with required thermal management solutions given the power dissipation characteristics. Check for RoHS3 compliance documentation prior to final integration.

Selection Notes

Select this component for applications requiring strict automotive quality standards and high current accuracy. The integrated switch reduces external component count compared to discrete solutions. Consider the 6V to 60V input range suitability for various vehicle electrical architectures. Evaluate thermal performance within the DFN-6 enclosure for the target environment.

Part Context

This part belongs to the ZXLD1366 series of LED drivers manufactured by Diodes Incorporated. The series includes variants with different packaging options such as TSOT-23-5 and SOIC-8. The QDACTC designation specifically denotes the automotive-qualified version in the DFN-6 package, distinguishing it from standard industrial grades.
