EV2351DQ-00A

4.75V to 23V Input, 1.5A Output

Step-Down DC/DC Converter

The Future of Analog IC Technology

EVALUATION BOARD - INITIAL RELEASE

GENERAL DESCRIPTION

FEATURES

The EV2351DQ-00A is the Evaluation Board for

MPS’ MP2351 Step-Down DC/DC Converter. It

features a wide supply range of 4.75V to 23V

and a continuous output current up to 1.5A. The

output voltage is set to 3.3V, but can be easily

adjusted to other levels from 1.22V. A 1.4MHz

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

10-pin QFN package minimizes board area.
