Overview
The AL5890-20P1-13 is a constant current LED driver IC manufactured by Diodes Incorporated. It utilizes a boost topology to regulate output current, supporting up to one output channel with a fixed 20 mA drive capability. The device operates within an input voltage range of 7 V to 400 V and can handle output voltages up to 400 V. It functions at a switching frequency of 20 kHz and is housed in a PowerDI123-2 package. The component is rated for operation between -40°C and +105°C.
Feature Summary
- Boost topology for high-voltage LED string driving
- Fixed 20 mA constant current regulation
- Wide input voltage range compatibility
Applications
- LED lighting systems requiring high input voltages
- Industrial LED indicator circuits
- Automotive exterior lighting modules
Procurement Notes
Verify end-of-life status before design finalization as the manufacturer has indicated obsolescence. Confirm availability through authorized distributors or secondary markets. Ensure RoHS compliance documentation is obtained. Validate that the PowerDI123-2 package meets thermal and mechanical requirements for the target application environment prior to procurement.
Selection Notes
Select this component when a boost converter architecture is required for high-voltage LED strings. The fixed 20 mA output suits low-power indicator applications. Consider the wide input voltage range for direct battery or line-powered designs. Evaluate thermal performance in the PowerDI123-2 package against system constraints.
Part Context
Part of the AL5890 series from Diodes Incorporated, designed for single-output LED drivers. The series offers various current options and packaging styles. This specific variant targets high-voltage applications using a compact surface-mount footprint suitable for automated assembly processes in consumer and industrial electronics.
Replacement Considerations
Check for active equivalents in the AL5890 family with different current ratings or packages. Verify pinout and electrical specifications match exactly. Consult manufacturer notices for recommended replacement parts if available.
