EV1593DN-00A (MP1593)

4.75V to 28V Input, Up to 3A Output

Step-Down DC/DC Converter

Monolithic Power Systems

EVALUATION BOARD - INITIAL RELEASE

GENERAL DESCRIPTION

FEATURES

The EV1593DN-00A is the Evaluation Board for

MPS’ MP1593 Step-Down DC/DC Converter. It

features a wide supply range of 4.75V to 28V

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 385KHz

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.
