Step 2
: Estimated Conversion Efficiency
Use the estimated full-load power conversion efficiency.
Typical value for an interleaved BCP PFC converter is in
the 0.92 to 0.98 range. The efficiency is in the lower half
of the range for low-power applications. Using state-of-
the-art semiconductors, good quality ferrite inductors
and   selecting   lower   limit   for   minimum   switching
frequency   positively   impacts   the   efficiency   of   the
system. In general, the value of 0.95 can be used
unless a more accurate power budget is available.

A margin of 20% has been added to the nominal output
power    to    cover    reference    inaccuracy,    internal
component   tolerances,   inductance   mismatch,   and
current-sense   resistor   variation   to   the   per-channel
power rating.
