GENERAL DESCRIPTION
The EV2354DS-00A is the Evaluation Board for
MPS’ MP2354 Step-Down DC/DC Converter. It
features a wide supply range of 4.75V to 23V
and a continuous output current up to 2A. The
output voltage is preset to 3.3V, but can be
easily adjusted to other levels from 1.22V. A
380KHz high switching frequency allows the
use of small, low cost capacitors and inductors.
Current mode control and an integrated power
MOSFET minimize component count, board area,
and solution cost. Fault condition protection
includes cycle-by-cycle current limiting, thermal
shutdown, and under-voltage lockout. Internal
soft-start reduces the turn-on stress. The small
but thermally enhanced 8-pin SOIC package
minimizes board area and provides excellent
thermal management.
