Gate Drive
?   The gate drive pattern should be wide enough to 
handle 1 A peak current.
?   Keep the controller as close to the MOSFETs as 
possible. This minimizes the length and the loop
area (series inductance) of the high-current gate
drive traces. The gate drive pattern should be as
short as possible to minimize interference.
Current Sensing
?   Current sensing should be as short as possible. 
?   To minimize switching noise, current sensing 
should not make a loop.
Input Voltage Sensing (V
IN
)
?   Since the impedance of voltage divider is large and 
FAN9612 detects the peak of the line voltage, the
VIN pin can be sensitive to the switching noise. The
trace connected to this pin should not cross traces
with high di/dt to minimize the interference.
?   The noise bypass capacitor for V
IN
 should be
connected as close to the pin as possible.
