DESCRIPTION
The EV3908DK-00J is an evaluation board for the
MP3908DK. It is configured to provide a regulated
3.3V output at up to 20A load current from a 36V-
75V input. The output is adjustable by changing
feedback resistors on the evaluation board.
MP3908DK features a synchronous gate output
which enables high efficiency design by drive the
clamp MOSFET.
