Description
The FSFR-series include highly integrated power
switches designed for high-efficiency half-bridge
resonant converters. Offering everything necessary to
build a reliable and robust resonant converter, the FSFR-
series simplifies designs and improves productivity, while
improving performance. The FSFR-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-series can be applied to various resonant
converter topologies, such as: series resonant, parallel
resonant, and LLC resonant converters.
