Overview
The AL5809-15S1-7 is a linear LED driver IC from Diodes Incorporated, designed for constant current regulation in lighting applications. It operates with an input voltage range of 2.5 V to 60 V and delivers a fixed output current of 15 mA. The device supports PWM dimming functionality within a frequency range of 100 Hz to 200 Hz. It features a maximum power dissipation of 360 mW and functions reliably across an extended temperature range from -40°C to +125°C. Packaged in a compact SOD-123-2 surface-mount format, it serves as a high-side or low-side regulator.
Feature Summary
- Provides stable constant current regulation for LED strings
- Supports pulse-width modulation dimming control
- Operates as either high-side or low-side current regulator
Applications
- LED lighting driver circuits
- General illumination systems
- Low-power indicator applications
Procurement Notes
Verify the specific suffix 'S1' confirms the SOD-123 package and 15 mA current rating, as variations exist within the AL5809 family. Confirm RoHS compliance status through official documentation before integration. Ensure supply chain sources provide genuine Diodes Incorporated components to guarantee thermal performance and electrical accuracy.
Selection Notes
Select this component when a fixed 15 mA output is required for single or series LED configurations. The linear topology suits applications where efficiency is secondary to simplicity and cost. Verify that the 360 mW power dissipation limit accommodates the voltage drop across the device in the target circuit design.
Part Context
This part belongs to the AL5809 series of constant current regulators. It shares functional similarities with variants like the AL5809-15P1-7, which utilizes a PowerDI-123 package for higher power handling. The S1 suffix specifically denotes the smaller SOD-123 footprint suitable for space-constrained designs.
Replacement Considerations
The AL5809-15P1-7 is a documented alternative offering identical electrical specifications but housed in a PowerDI-123 package for improved thermal performance.
