The FSFR2100 is a highly integrated power switch for high energy efficiency half-bridge resonant converters. The FSFR2100 provides everything needed to build a reliable and robust resonant converter, simplifying design and increasing productivity and performance. The FSFR2100 combines a power MOSFET with fast recovery type body diode, high side gate drive circuit, accurate current controlled oscillator, frequency limit circuit, soft start and built-in protection functions. This high-side gate drive circuit features common-mode noise suppression, ensuring stable operation and excellent noise immunity. The fast recovery body diode of the MOSFET increases reliability during abnormal operating conditions while minimizing the effect of reverse recovery. The use of Zero Voltage Switching (ZVS) technology greatly reduces switching losses and greatly improves energy efficiency. ZVS also significantly reduces switching noise, allowing the use of small electromagnetic interference (EMI) filters. The FSFR2100 can be applied in various resonant converter topologies such as series resonant, parallel resonant and LLC resonant converters.
