ZXLD1371EST16TC

Overview

The ZXLD1371EST16TC is a high-efficiency, constant-current LED driver from Diodes Incorporated. It integrates a power switch and operates in buck or boost topology to regulate LED current. The device features an internal oscillator for fixed-frequency operation and supports dimming via analog or PWM signals. It includes comprehensive protection mechanisms such as over-temperature shutdown, open-load detection, and short-circuit protection. The EST16 package provides thermal efficiency for compact designs.

Feature Summary

• Integrated high-side power switch eliminates external MOSFET requirements
• Supports flexible dimming control through analog voltage or pulse-width modulation inputs
• Includes built-in safety features like thermal shutdown and fault detection

Applications

• General illumination lighting systems
• Automotive interior and exterior lighting modules
• Portable electronic device backlighting

Procurement Notes

Verify the exact suffix EST16TC against the manufacturer's latest datasheet to confirm pinout and thermal pad configuration. Ensure compatibility with your PCB layout regarding the exposed pad connection for heat dissipation. Cross-reference the ordering code with authorized distributors to avoid counterfeit components.

Selection Notes

Choose this component when a compact solution with integrated switching is required for LED current regulation. Consider the input voltage range and desired output current capabilities relative to your LED string configuration. Evaluate thermal performance needs based on the ambient operating conditions and enclosure constraints.

Part Context
