FSFR2100

FAIRCHILD SEMICONDUCTOR  FSFR2100  电源负载开关, 用于半桥共振转换器, 1路输出, SIP-9

The is a 600V Integrated Power Switch FPS™ for 450W half-bridge resonant converter. Offering everything necessary to build a reliable and robust resonant converter, the FSFR2100 simplifies designs and improves productivity, while improving performance. The FSFR2100 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.
