GENERAL DESCRIPTION
The EV2355DN-00A is the Evaluation Board for
MPS’ MP2355 Step-Down DC/DC Converter. It
features a wide supply range of 4.75V to 23V
and a continuous output current up to 3A. The
output voltage is set 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
8-pin SOIC package with exposed pad minimizes
board area and provides excellent thermal
management.
