2 / 15 page December 2010 © 2010 Fairchild Semiconductor Corporation www.fairchildsemi.com FLS-XS Series • Rev.1.0.0 FLS-XS Series — Half-Bridge LLC Resonant Control IC for Lighting Features Variable Frequency Control with 50% Duty Cycle for Half-Bridge Resonant Converter Topology High Efficiency through Zero Voltage Switching (ZVS) Internal UniFET™ with Fast-Recovery Body Diode Fixed Dead Time (350ns) Optimized for MOSFETs Up to 300kHz Operating Frequency Auto-Restart Operation for All Protections with External LVCC Protection Functions: Over-Voltage Protection (OVP), Over-Current Protection (OCP), Abnormal Over- Current Protection (AOCP), Internal Thermal Shutdown (TSD) Applications General LED Lighting Power Industrial, Commercial, and Residential LED Lighting Fixtures Outdoor Lighting: Street, Roadway, Parking, Construction and Ornamental LED Lighting Fixtures Description The FLS-XS series of general lighting power controllers includes highly integrated power switches for medium- to high-power lumens applications. Offering everything necessary to build a reliable and robust half-bridge resonant converter, the FLS-XS series simplifies designs and improves productivity, while improving performance. The FLS-XS series combines power MOSFETs with fast- recovery type body diodes, a high-side gate-drive circuit, an accurate current controlled oscillator, frequency limit circuit, soft-start, and built-in protection functions. The high-side gate-drive circuit has common-mode noise cancellation capability, which guarantees stable operation with excellent noise immunity. The fast- recovery body diode of the MOSFETs improves reliability against abnormal operation conditions, while minimizing the effect of reverse recovery. Using zero voltage switching (ZVS) dramatically reduces the switching losses and significantly improves efficiency. ZVS also reduces switching noise noticeably, which allows a small- sized Electromagnetic Interference (EMI) filter. The FLS-XS series can be applied to resonant converter topologies such as series resonant, parallel resonant, and LLC resonant converters.
