Overview
The AL5809-30S1-7 is a linear LED driver IC from Diodes Incorporated, designed for high-voltage applications with an integrated switch. It operates within an input voltage range of 2.5 V to 60 V and delivers a fixed output current of 30 mA. The device supports PWM dimming at frequencies between 100 Hz and 200 Hz. It functions in a single-channel topology and is housed in a compact SOD-123-2 surface-mount package. The component is rated for operation across a temperature range of -40°C to +125°C, ensuring reliability in demanding environments.
Feature Summary
- Integrates a high-voltage internal switch for simplified circuit design
- Supports precise PWM dimming control for brightness adjustment
- Provides stable constant current regulation for LED loads
Applications
- LED lighting driver circuits
- General illumination systems
- High-voltage LED string driving
Procurement Notes
Verify the specific suffix 'S1' confirms the SOD-123-2 package and 30 mA current rating against the official datasheet. Confirm RoHS compliance status and AEC-Q100 qualification requirements if automotive use is intended. Ensure the ordering code matches the exact manufacturer part number to avoid functional discrepancies.
Selection Notes
Select this component when a linear topology is suitable for the application's power dissipation constraints. The 30 mA output current defines the LED load capacity. Verify that the system input voltage remains within the 2.5 V to 60 V operational window. Consider thermal management requirements due to the linear regulation method and available package power handling capabilities.
Part Context
This part belongs to the AL5809 series of linear LED drivers manufactured by Diodes Incorporated. The series offers various fixed current options and packaging styles to suit different LED driving needs. The AL5809-30S1-7 specifically targets applications requiring a 30 mA drive current in a small form factor.
Replacement Considerations
Check for other AL5809 variants with different current ratings or packages if electrical parameters do not match. Verify pinout compatibility before substituting with similar linear LED drivers from other manufacturers.
