5.3 Over-Voltage Protection (OVP) : When the LV CC
reaches 23 V, OVP is triggered. This protection is used
when auxiliary winding of the transformer to supply V CC
to the FPS? is utilized.
5.4 Thermal Shutdown (TSD) : The MOSFETs and
the control IC in one package makes it easier for the
control IC to detect the abnormal over-temperature of
the MOSFETs. If the temperature exceeds
approximately 130 ? C, thermal shutdown triggers.
6. Current Sensing Using a Resistor: FSFR-XS series
senses drain current as a negative voltage, as shown in
Figure 23 and Figure 24. Half-wave sensing allows low
power dissipation in the sensing resistor, while full-wave
sensing has less switching noise in the sensing signal.

7. PCB Layout Guidelines : Duty imbalance problems
may occur due to the radiated noise from the main
transformer, the inequality of the secondary side leakage
inductances of main transformer, and so on. This is one
of the reasons that the control components in the vicinity
of R T pin are enclosed by the primary current flow pattern
on PCB layout. The direction of the magnetic field on the
components caused by the primary current flow is
changed when the high- and low-side MOSFET turn on
by turns. The magnetic fields with opposite directions
induce a current through, into, or out of the R T pin, which
makes the turn-on duration of each MOSFET different. It
is strongly recommended to separate the control
components in the vicinity of R T pin from the primary
current flow pattern on PCB layout. Figure 25 shows an
example for the duty-balanced case.
