GENERAL DESCRIPTION
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.
