CAUTION
This evaluation board uses high voltages and currents. Extreme
caution must be taken especially on the primary side to ensure
safety for the user. It is strongly advised to power down the
evaluation board when not in use. A current limited power
supply is recommended as an input because no fuse is present
on the board.

GENERAL DESCRIPTION
This evaluation board features the
can be interfaced to any PC running
Windows® 2000, Windows NT, or Windows XP via the computer's
USB port. The evaluation board allows all the input and output
functions of the
USB port. The evaluation board allows all the input and output
functions of the
to be exercised without the need for
internal registers. The board is set up for
the
to act as an isolated switching power supply with
a rated load of 12 V/25 A from an input voltage ranging from
350 V dc to 400 V dc.
350 V dc to 400 V dc.
