ZXLD1366DACTC

Overview

The ZXLD1366DACTC is a single-channel LED lighting driver IC from Diodes Incorporated, featuring an integrated high-side switch and buck topology. It operates within a supply voltage range of 6 V to 60 V, delivering a regulated output current of 1 A. The device supports PWM dimming and includes open LED protection. It utilizes a fixed switching frequency of 1 MHz and provides an output voltage capability up to 65 V. The component is housed in a compact V-DFN3030-6 package with an exposed pad for thermal management. It functions reliably across an operating temperature range of -40°C to +125°C.

Feature Summary

• Integrates a high-side power switch within a continuous mode inductive step-down converter architecture.
• Supports precise PWM dimming control for efficient light regulation.
• Includes built-in open LED protection to enhance system reliability.

Applications

• General illumination systems
• Signage applications

Procurement Notes

Verify the specific suffix (DACTC) against the manufacturer's official datasheet to confirm the exact packaging configuration, such as cut tape or reel quantities. Ensure compatibility with surface-mount assembly processes given the V-DFN3030-6 package type. Cross-reference RoHS compliance status with the latest environmental declarations provided by Diodes Incorporated before finalizing procurement specifications.

Selection Notes

Select this component when designing circuits requiring a single-channel buck converter for driving series-connected LEDs from a wide input voltage range. The integrated switch simplifies bill of materials by reducing external component count. Consider the 1 MHz switching frequency for balancing efficiency and passive component size. Verify that the thermal performance of the DFN package meets the application's heat dissipation requirements under maximum load conditions.

Part Context

This part belongs to the ZXLD1366 family of LED drivers designed for efficient constant current regulation. The DACTC suffix typically denotes a specific tape and reel or cut tape variant of the base ZXLD1366 device. It is categorized under PMIC LED drivers and is intended for automotive and industrial lighting applications where robust protection features and wide input voltage tolerance are required.

Replacement Considerations

Consult the official datasheet for direct pin-to-pin compatible alternatives within the same product family. Verify that any substitute maintains the 1 A output current rating and 60 V input voltage specification. Ensure the replacement package matches the V-DFN3030-6 footprint if board space is constrained.
