Description
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 FSFR-
US 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.
