The Future of Analog IC Technology
GENERAL DESCRIPTION
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.
