ASL2416SHNY

Overview

The ASL2416SHNY is a two-channel buck mode LED driver IC from NXP Semiconductors. It delivers constant average DC current to LEDs independent of the input voltage. The device supports PWM dimming and provides two outputs with a maximum current of 1.5A per channel. It is housed in a 32-HVQFN (5x5) package. The component complies with European Union environmental standards, having passed ROHS certification and the REACH directive.

Feature Summary

• Two-channel buck mode architecture for independent LED control
• Constant average DC current delivery independent of input voltage variations
• Supports PWM dimming functionality for brightness control

Applications

• Automotive lighting systems
• LED driver IC applications
• Avionics power management

Procurement Notes

Verify the specific suffix 'Y' indicates compliance with RoHS and REACH directives as documented by NXP. Confirm the package type is 32-HVQFN (5x5). Ensure the source document explicitly links this part number to automotive-grade specifications. Cross-reference the manufacturer identifier as NXP USA Inc. or NXP Semiconductors depending on the official datasheet header.

Selection Notes

Select this component for applications requiring dual-channel constant current regulation in automotive environments. The buck topology suits input voltages higher than the LED string requirements. Verify thermal performance within the HVQFN package constraints. Ensure PWM dimming interface compatibility with the system controller.

Part Context

This part belongs to the ASL241ySHN family of dual-channel automotive LED buck drivers. It complements other NXP solutions like the ASL341ySHN three-channel variant. The series targets automotive lighting and avionics sectors requiring reliable LED current regulation.
