Supports step-down (buck) and step-up (boost) topologies
Designed specifically for LED driver applications

Applications

LED driver circuits
Constant-frequency boost control systems
Integrated buck-boost power management

Procurement Notes

Verify availability status carefully as this part is listed as obsolete. Confirm final unit compatibility with existing designs before procurement attempts. Check for authorized distributors or remaining stock from previous production runs. Ensure the 16-SOIC package matches the target PCB footprint. Review datasheet revisions for any historical design notes.

Selection Notes

Select this component only if the design requires an integrated boost and buck solution for LED driving. Verify that the 16-SOIC package is compatible with the assembly process. Consider the obsolete status when planning long-term production. Ensure the application supports the specific constant-frequency operation mode defined in the official documentation.
