Description
The FSFR-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-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.

Description
This is the drain of the high-side MOSFET, typically connected to the input DC link voltage.
This pin is for enable/disable and protection. When the voltage of this pin is above 0.6V, the
IC operation is enabled. When the voltage of this pin drops below 0.4V, gate drive signals
for both MOSFETs are disabled. When the voltage of this pin increases above 5V,
protection is triggered.
This pin programs the switching frequency. Typically, an opto-coupler is connected to
control the switching frequency for the output voltage regulation.
This pin senses the current flowing through the low-side MOSFET. Typically, negative
voltage is applied on this pin.
This pin is the control ground.
This pin is the power ground. This pin is connected to the source of the low-side MOSFET.
This pin is the supply voltage of the control IC.
No connection.
This is the supply voltage of the high-side gate-drive circuit IC.
This is the drain of the low-side MOSFET. Typically, a transformer is connected to this pin.
