Description
FSFR-series is a highly integrated power switch family
specially 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 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
the efficiency is significantly improved. The ZVS also
reduces the switching noise noticeably, which allows a
small-sized 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 pin is the drain of the high-side MOSFET. It is 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 pin is the supply voltage of the high-side drive circuit IC.
This pin is the drain of the low-side MOSFET. Typically, a transformer is connected
to this pin.

Absolute Maximum Ratings
Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be
operable above the recommended operating conditions and stressing the parts to these levels is not recommended. In
addition, extended exposure to stresses above the recommended operating conditions may affect device reliability.
The absolute maximum ratings are stress ratings only. T
