Design example using the L6562A FOT PFC Excel
spreadsheet
An Excel spreadsheet has been developed to allow a quick and easy design of a boost PFC
pre-regulator using the STM L6562A controller, operating in fixed off-time.
Figure 18
shows the first sheet already precompiled with the input design data used in the
previous Section 4: Designing a fixed off-time PFC.

Other design data
The tool is able to generate a complete part list of the PFC schematic represented in
Figure 20
, including the power dissipation calculation of the main components.
