SSL1523P/N2,112

Overview

The SSL1523P/N2,112 is an AC/DC offline switch IC designed for non-dimmable LED driver applications. It utilizes a flyback topology with an internal power switch and supports a supply voltage range of 80V to 276V. The device operates at frequencies between 10kHz and 200kHz, delivering up to 2A output current per channel. Packaged in an 8-DIP (0.300") through-hole format, it is rated for junction temperatures from -40°C to 145°C.

Feature Summary

• Integrated high-voltage startup circuitry for simplified design
• Built-in frequency jittering to reduce electromagnetic interference
• Comprehensive protection features including overvoltage and thermal shutdown

Applications

• Non-dimmable LED lighting systems

Procurement Notes

Verify the specific ordering suffix N2,112 against official NXP documentation to ensure correct package and tape/reel specifications. Confirm RoHS compliance status as required by project regulations. Check component availability and lifecycle status, as this part may be subject to discontinuation or replacement notices. Ensure compatibility with existing PCB footprints and assembly processes before finalizing procurement orders.

Selection Notes

Select this component for designs requiring a single-output flyback converter with integrated switching capabilities. Consider the 8-DIP package for through-hole mounting requirements and the specified operating temperature range. Evaluate the maximum output current and input voltage limits against the target LED load characteristics. Verify that the fixed-frequency operation aligns with EMI constraints for the intended application environment.
