Overview
The AL5810FJ3-7 is a linear LED driver IC from Diodes Incorporated, housed in a W-DFN2020-3 package. It supports an input voltage range of 2 V to 60 V and delivers a constant output current of 200 mA. The device features PWM dimming capability with a frequency range of 100 Hz to 200 Hz. It operates within a temperature range of -40°C to +105°C and has a maximum power dissipation of 2 W. The open-drain output allows for flexible integration into LED lighting systems.
Feature Summary
- Supports wide input voltage range from 2 V to 60 V
- Enables precise current regulation via external resistor
- Provides PWM dimming functionality for brightness control
Applications
- General LED lighting fixtures
- LED backlighting modules
- Low-voltage LED strip drivers
Procurement Notes
Verify the specific suffix FJ3 corresponds to the W-DFN2020-3 package and tape-and-reel quantity when ordering. Confirm RoHS compliance status through official manufacturer documentation prior to procurement. Ensure thermal management design accounts for the 2 W power dissipation limit in the final application environment.
Selection Notes
Select this component for applications requiring simple linear regulation with low component count. The fixed 200 mA output current suits single or series-connected LED strings where voltage drop is within the 60 V limit. Consider the W-DFN2020-3 package size constraints for PCB layout. Verify that the required dimming frequency falls within the 100 Hz to 200 Hz operational window.
Part Context
This part belongs to the AL5810Q series of adjustable linear LED drivers. It is designed as a cost-effective solution for driving LEDs in compact spaces. The FJ3 marking indicates the specific package variant and manufacturing batch code associated with the W-DFN2020-3 footprint.
Replacement Considerations
Check datasheets for pin-compatible alternatives within the same linear driver family. Verify that substitute parts maintain the 200 mA output current and 60 V maximum voltage rating. Ensure thermal performance characteristics match the original specification for direct replacement scenarios.
