FSFR1700US

200W - Fairchild Power Switch (FPS) for Half-Bridge Resonant Converters

Not Recommended For New Design as of 17-Feb-2011

    The FSFR-US series are a highly integrated power switches designed for high-efficiency half-bridge resonant converters. Offering everything necessary to build a reliable and robust resonant converter, the FSFRUS series simplifies designs and improves productivity, while improving performance. The FSFR-US 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 a 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 the reverse recovery. Using the zero-voltage-switching (ZVS) technique dramatically reduces the switching losses and efficiency is significantly improved. The ZVS also reduces the switching noise noticeably, which allows a small-sized Electromagnetic Interference (EMI) filter.

              The FSFR-US series can be applied to various resonant converter topologies such as series resonant, parallel resonant, and LLC resonant converters.      • Variable Frequency Control with 50% Duty Cycle for Half-Bridge Resonant Converter Topology• High Efficiency through Zero Voltage Switching (ZVS)• Internal UniFETs with Fast-Recovery Type Body Diode• Fixed Dead Time (350ns) Optimized for MOSFETs• Up to 300kHz Operating Frequency• Auto-Restart Operation for All Protections with An External LVCC• Protection Functions: Over-Voltage Protection (OVP), Over-Current Protection (OCP), Abnormal Over-Current Protection (AOCP), Internal Thermal Shutdown (TSD)
