AL9910-5SP-13

Overview

The AL9910-5SP-13 is a high-voltage LED driver IC from Diodes Incorporated, designed for universal input AC mains applications. It operates within an input voltage range of 85 VAC to 277 VAC and supports a switching frequency up to 300 kHz, determined by a single external resistor. The device features a SOIC-8 surface-mount package and functions as a current sink with a maximum power dissipation of 2.2 W. It includes comprehensive protection mechanisms such as overvoltage, short-circuit, and overtemperature safeguards.

Feature Summary

• Integrates overvoltage, short-circuit, and overtemperature protection circuits
• Supports switching frequencies up to 300 kHz via a single resistor
• Designed for universal high-voltage AC input operation

Applications

• General lighting systems
• LED signage
• Backlighting solutions

Procurement Notes

Verify the specific suffix (e.g., -5SP-13) against official Diodes Incorporated documentation to confirm pinout compatibility and packaging specifications. Ensure that the selected variant matches the required thermal management capabilities for the intended application environment. Cross-reference datasheet revisions to confirm any changes in electrical characteristics or recommended operating conditions prior to final procurement decisions.

Selection Notes

Select this component for designs requiring a compact, non-isolated LED driver solution with integrated protection features. The SOIC-8 package suits space-constrained PCB layouts. Consider the 2.2 W power dissipation limit when designing thermal paths. Verify that the external MOSFET selection aligns with the driver's output capabilities and the target switching frequency determined by the timing resistor.

Part Context

This part belongs to the AL99 series of LED drivers from Diodes Incorporated, which are engineered for high-brightness LED applications. The series typically offers cost-effective solutions for replacing traditional lighting sources.
