The value of resistor R5 will have to be adjusted in some designs and
as a guideline the value from the following calculation can be used:
P
O
Maximum continuous output power in watts.
V
O
Nominal PFC output voltage in volts.
C
O
PFC output capacitance in farads.

Heat Sinking and Thermal Design
Figures 15, 16, 17 show an example of the recommended assembly
for the HiperPFS-3. In this assembly, no insulation pad is required
and HiperPFS-3 can be directly connected to the heat sink by
mechanical clip or adhesive thermal compound.
The HiperPFS-3 back metal is electrically connected to the heat sink
and the heat sink is required to be connected to the HiperPFS-3
source terminal in order to reduce EMI.
