ZXLD1356QET5TA

Overview

The ZXLD1356QET5TA is a single-channel LED lighting driver IC manufactured by Diodes Incorporated. It functions as a continuous mode inductive step-down (buck) converter designed for driving single or multiple series-connected LEDs efficiently. The device integrates an internal power switch and supports PWM dimming capabilities. It operates within an input voltage range of 6V to 60V, delivering a regulated output current of 550mA. The component is housed in a TSOT-25 package and is qualified to AEC-Q100 standards for automotive applications.

Feature Summary

Integrates an internal high-voltage power switch for compact design
Supports PWM dimming for precise brightness control
Includes open LED protection for enhanced system reliability

Applications

Automotive exterior lighting systems
LED headlamp modules
General LED illumination drivers

Procurement Notes

Verify the specific suffix 'QET5TA' against official Diodes Incorporated documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with existing PCB footprints for the TSOT-25 form factor. Confirm that the intended application environment meets the specified operating temperature range and electrical requirements before finalizing procurement orders.

Selection Notes

Select this component for applications requiring a buck topology with integrated switching capability. It is suitable for designs needing regulation of series-connected LED strings from a wide input voltage range. Consider the thermal performance within the TSOT-25 package relative to the expected load current and ambient conditions when evaluating suitability for the target design.

Part Context

This part belongs to the ZXLD1356 family of LED drivers from Diodes Incorporated. The family includes variants such as ZXLD1356DACTC, which utilizes a DFN-6 package instead of the TSOT-25 configuration found in the QET5TA variant. These components share core functional characteristics but differ in physical packaging and potentially thermal dissipation properties.
