Description
In this data brief of the EVL6566A-75WADP demo
board, the main characteristics and features of a
75 W adapter wide-range input mains, power-
factor-corrected AC-DC adapter using the new
L6566A controller and the L6563 dedicated to the
PFC stage are described.
High efficiency and the very low standby input
consumption are highlighted in the following
figures and tables. The board is programmed for
working at fixed frequency (65 kHz) under
nominal condition (19 V at 4 A).
On the secondary side the TSM1014 with a
precise voltage reference and the optocoupler
SFH617A-4 to transfer the error amplifiers
information to the primary side have been used.
