Description
This demonstration board is based on the new
transition-mode PFC controller L6564H and
implements a 100 W, wide-range mains input,
PFC pre-conditioner suitable for ballast, adapters,
flat screen displays, and all SMPS having to meet
IEC61000-3-2 or JEITA-MITI regulations.
The L6564H is a current-mode PFC controller
operating in transition mode (TM) which embeds
the same features existing in the L6564 with the
addition of a high voltage startup source. These
functions make the IC especially suitable for
applications that must be compliant with energy
saving regulations and where the PFC pre-
regulator works as the master stage.
The EVAL6564H-100W implements a power
factor correction (PFC) pre-regulator 100 W,
continuous power, on a regulated 400 V rail from
a wide-range mains voltage and providing for the
reduction of the mains harmonics, allowing the
European EN61000-3-2 or the Japanese JEITA-
MITI standard to be met. The regulated output
voltage is typically the input for the cascaded
