EV2354DS-00A

4.75V to 23V IN, 2A OUT, 380KHz

Step-Down DC/DC Converter

Monolithic Power Systems

EVALUATION BOARD

GENERAL DESCRIPTION

FEATURES

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.
