Description
The FSFR-series include highly integrated power
switches
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
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
conditions, while minimizing the effect of the reverse
recovery.
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.
