ZXLD1356QDACTC

Overview

The ZXLD1356QDACTC is a single-output, step-down (buck) DC-DC LED driver IC from Diodes Incorporated. It operates as a continuous mode inductive converter designed for driving single or multiple series-connected LEDs efficiently. The device features an internal switch rated for 60V and supports a maximum output current of 550mA. It includes PWM dimming capability for brightness control. The component is housed in a V-DFN3030-6 package.

Feature Summary

• Integrated internal high-voltage switch for simplified circuit design
• Continuous conduction mode operation for efficient LED driving
• Supports PWM dimming for precise brightness adjustment

Applications

• Automotive exterior lighting systems
• Automotive interior ambient lighting
• General LED illumination modules requiring buck topology

Procurement Notes

Verify the specific suffix 'Q' indicates automotive grade qualification and 'TC' denotes tape and reel packaging configuration. Confirm the manufacturer is Diodes Incorporated. Ensure the datasheet matches the ZXLD1356Q family specifications. Check for RoHS compliance status if required by your assembly process. Validate the package type is V-DFN3030-6.

Selection Notes

Select this component when a compact, high-efficiency buck regulator is needed for LED strings. It is suitable for applications requiring integrated switching elements to reduce external component count. Consider the 60V voltage rating and 550mA current limit against your load requirements. Ensure thermal management aligns with the DFN package capabilities.
