Overview
The AL5890-40D-13 is a constant current LED driver IC from Diodes Incorporated, designed for high-voltage applications. It operates with an input voltage range of 7 V to 400 V and supports output voltages up to 400 V. The device provides a fixed output current of 40 mA through a single channel using a boost topology. It is housed in a TO-252-3 surface-mount package and functions within a temperature range of -40°C to +105°C. Key electrical specifications include thermal foldback protection and compatibility with standard SMD/SMT mounting techniques.
Feature Summary
- Integrates thermal foldback protection to manage heat dissipation under varying load conditions
- Supports wide input voltage ranges suitable for high-voltage LED string configurations
- Provides stable constant current output for consistent LED brightness control
Applications
- High-voltage LED lighting systems
- Industrial LED signage drivers
- Automotive exterior lighting circuits
Procurement Notes
Verify the specific suffix D-13 against official Diodes Incorporated documentation to confirm pinout and packaging details. Confirm RoHS compliance status via the manufacturer's latest datasheet or environmental declaration. Ensure the TO-252-3 package dimensions match your PCB footprint requirements before finalizing procurement orders.
Selection Notes
Select this component when designing circuits requiring a single-channel boost converter for high-voltage LED arrays. The 40 mA output current rating suits low-power indicator or signaling applications rather than high-intensity illumination. Consider the operating temperature range if the deployment environment exceeds standard commercial limits.
Part Context
This part belongs to the AL5890 series of linear and switching LED drivers offered by Diodes Incorporated. The series targets cost-sensitive lighting solutions where compact form factors are essential. The AL5890-40D-13 specifically addresses high-voltage needs within this portfolio, distinguishing itself from lower-voltage variants in the same family.
Replacement Considerations
Check for AL5890-15D-13 if a lower current rating is acceptable. Verify cross-reference availability with other manufacturers offering similar boost-topology LED drivers in TO-252 packages.
