AL5809-20S1-7

Overview

The AL5809-20S1-7 is a linear LED driver IC from Diodes Incorporated, designed for high-voltage applications with an integrated high-side switch. It delivers a constant output current of 20 mA and supports an input voltage range from 2.5 V to 60 V. The device features PWM dimming capability and operates within a temperature range of -40°C to +125°C. Packaged in a compact SOD-123-2 surface-mount format, it dissipates up to 360 mW of power.

Feature Summary

• Supports PWM dimming for precise brightness control
• Integrates a high-side switch for simplified circuit design
• Operates with wide input voltage flexibility

Applications

• LED lighting modules
• Backlighting systems
• Indicator circuits

Procurement Notes

Verify the specific suffix 'S1' confirms the SOD-123 package and 20 mA current rating against official Diodes Incorporated documentation. Ensure compatibility with the required thermal dissipation limits for the target application environment before finalizing procurement specifications.

Selection Notes

Select this component when a linear topology is preferred for low-noise LED driving. The SOD-123 package suits space-constrained designs requiring surface-mount installation. Confirm that the 360 mW power dissipation capability aligns with the thermal requirements of the intended PCB layout.

Part Context

This part belongs to the AL5809 series of linear LED drivers. It shares functional characteristics with other variants in the family but differs in output current settings and physical packaging options. The series targets general-purpose LED illumination tasks requiring reliable constant current regulation.

Replacement Considerations

Substitutes must match the 20 mA output current and SOD-123-2 package dimensions. Verify equivalent input voltage ranges and thermal performance characteristics to ensure functional parity in existing designs.
