SSL2102T/N1,518

Overview

The SSL2102T/N1,518 is a fully integrated LED driver IC designed for mains-powered lighting applications. It operates as a Switched Mode Power Supply (SMPS) controller optimized for dimmable LED lamps up to 25 W. The device features an integrated circuit that allows direct start-up from rectified mains voltage. It provides phase-cut dimming compatibility when connected to standard dimmers. The component is housed in a 20-pin SO package and supports various output voltages including 9V, 12V, 15V, 18V, and 24V configurations.

Feature Summary

• Fully integrated AC/DC LED driver solution for mains-powered applications
• Supports phase-cut dimming with optimized dimming curve circuitry
• Enables direct start-up from rectified mains voltage
• Suitable for lamp designs up to 25 W power rating

Applications

• Dimmable LED downlights
• LED spotlights and GU10 lamps
• E27 screw-base LED bulbs
• PARx LED lamp modules

Procurement Notes

Verify the specific suffix N1,518 against official NXP documentation to confirm tape-and-reel packaging specifications and moisture sensitivity level. Ensure the ordering part number matches the exact package variant required for your PCB layout. Cross-reference the datasheet revision date to confirm compliance with current regulatory standards for LED drivers.

Selection Notes

Select this component for non-isolated or isolated LED driver topologies requiring integrated control. It is appropriate for designs needing built-in dimming compatibility without external microcontrollers. Consider thermal management requirements for the 20-pin SO package. Evaluate input voltage range compatibility with local mains standards before finalizing the design.

Part Context

The SSL2102 belongs to NXP's SSL21xx family of SMPS controllers for LED lighting. It serves as a mid-range solution between the lower-power SSL2101 and the higher-power SSL2103. This series is engineered for cost-effective, high-performance lighting applications. The T/N1,518 designation indicates a specific reel quantity and package configuration within the broader SSL2102 product line.

Replacement Considerations

Direct pin-compatible replacements may include other members of the SSL21xx family such as the SSL2101 or SSL2103, depending on power requirements. Verify functional equivalence for dimming curves and startup behavior. Check for updated package options or improved thermal performance in newer revisions.
