Is Now Part of To learn more about ON Semiconductor, please visit our website at www.onsemi.com Please note: As part of the Fairchild Semiconductor integration, some of the Fairchild orderable part numbers will need to change in order to meet ON Semiconductors system requirements. Since the ON Semiconductor product management systems do not have the ability to manage part nomenclature that utilizes an underscore ( ), the underscore ( ) in the Fairchild part numbers will be changed to a dash (-). This document may contain device numbers with an underscore ( ). Please check the ON Semiconductor website to verify the updated device numbers. The most current and up-to-date ordering information can be found at www.onsemi.com. Please email any questions regarding the system integration to Fairchild questions onsemi.com.

Offering everything High Efficiency through Zero Voltage Switching (ZVS) necessary to build a reliable and robust half-bridge resonant converter, the FLS-XS series simplifies designs Internal UniFET with Fast-Recovery Body Diode and improves productivity, while improving performance. Fixed Dead Time (350ns) Optimized for MOSFETs The FLS-XS series combines power MOSFETs with fast- recovery type body diodes, a high-side gate-drive circuit, Up to 300kHz Operating Frequency an accurate current controlled oscillator, frequency limit Auto-Restart Operation for All Protections with circuit, soft-start, and built-in protection functions. The External LVCC high-side gate-drive circuit has common-mode noise cancellation capability, which guarantees stable Protection Functions: Over-Voltage Protection (OVP), operation with excellent noise immunity. The fast- Over-Current Protection (OCP), Abnormal Over- recovery body diode of the MOSFETs improves reliability Current Protection (AOCP), Internal Thermal against abnormal operation conditions, while minimizing Shutdown (TSD) the effect of reverse recovery. Using zero voltage switching (ZVS) dramatically reduces the switching Applications losses and significantly improves efficiency. ZVS also reduces switching noise noticeably, which allows a small- General LED Lighting Power sized Electromagnetic Interference (EMI) filter. Industrial, Commercial, and Residential LED The FLS-XS series can be applied to resonant converter Lighting Fixtures topologies such as series resonant, parallel resonant, Outdoor Lighting: Street, Roadway, Parking, and LLC resonant converters.
