AL9910-6S-13

Overview

The AL9910-6S-13 is a constant current LED driver IC designed for high-power LED applications. It operates in a buck converter topology to regulate LED current with high accuracy. The device features an internal power switch and supports dimming control via PWM or analog methods. Key electrical parameters include a wide input voltage range, adjustable output current up to 1A, and integrated protection functions such as over-temperature and open/short circuit detection. The -6S suffix indicates the specific package configuration.

Feature Summary

• Integrated high-side N-channel power switch for simplified external component count
• Supports both PWM and analog dimming interfaces for flexible brightness control
• Built-in thermal shutdown and fault protection mechanisms for enhanced reliability

Applications

• General illumination lighting fixtures
• Automotive interior and exterior lighting systems
• Portable battery-powered LED lamps

Procurement Notes

Verify the exact ordering code against manufacturer documentation to ensure correct package type and tape/reel specifications. Confirm that the -13 suffix aligns with standard packaging requirements for your assembly line. Cross-reference pin assignments with the official datasheet schematic before PCB layout finalization to prevent integration errors.

Selection Notes

Choose this component when a compact solution for driving high-power LEDs from a variable DC source is required. Evaluate the maximum input voltage and desired LED string current against the device limits. Consider the thermal management capabilities of the intended PCB footprint and ambient operating conditions.
