AL5890-10P1-13

Overview

The AL5890-10P1-13 is a constant current LED driver manufactured by Diodes Incorporated, designed for high-voltage boost applications. It delivers a fixed output current of 10 mA with a maximum supply voltage of 400 V and an output voltage capability up to 400 V. The device operates within a frequency range of 20 kHz and functions across a temperature range from -40°C to +105°C. Packaged in a PowerDI123-2 surface-mount format, this single-output linear driver integrates internal switching components to facilitate efficient LED illumination control in compact designs.

Feature Summary

• Integrates high-voltage boost topology for driving LEDs without external power switches
• Provides precise constant current regulation for stable LED brightness
• Utilizes compact PowerDI123-2 package for space-constrained PCB layouts

Applications

• LED lighting modules requiring high input voltage headroom
• Backlight drivers for displays operating under boost conditions
• General-purpose LED illumination circuits with limited board space

Procurement Notes

Verify component authenticity through authorized Diodes Incorporated distributors or certified partners. Confirm the specific suffix P1-13 matches required packaging specifications. Check current lifecycle status as end-of-life notifications may impact long-term availability. Ensure compliance with RoHS directives if applicable to your region. Validate that the 400V rating aligns with your system's electrical requirements before procurement.

Selection Notes

Select this component when a fixed 10 mA drive current is sufficient for the target LED array. Consider the 400V maximum voltage limit to ensure compatibility with series-connected LED configurations. Evaluate the PowerDI123-2 footprint against available PCB real estate. Compare thermal performance at +105°C max junction temperature against ambient operating conditions. Verify that the 20 kHz switching frequency does not interfere with sensitive analog sections of the design.

Part Context

This part belongs to the AL5890 series of LED drivers from Diodes Incorporated, which focuses on high-voltage solutions. Unlike the AL5809 series which offers lower voltage ratings and different current options, the AL5890 series is optimized for higher voltage boost applications. The specific model AL5890-10P1-13 denotes the 10 mA current variant in the standard reel packaging configuration.

Replacement Considerations

Direct substitutes include other AL5890 variants with different current settings such as AL5890-15P1-13 or AL5890-20P1-13 if current adjustment is permissible. Cross-reference with similar high-voltage boost LED drivers from other manufacturers only if pinout and electrical characteristics are identical.
