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 

isolated DC-DC converter that provides the output 
rails required by the load.
