DESCRIPTION

The EV2358DS-00A is the evaluation board for

the MP2358, a monolithic step-down switch

mode converter with a built in internal power

MOSFET. It achieves 2A continuous output

current over a wide input supply range with

excellent load and line regulation.

The MP2358 employs current mode operation

for

fast

transient

response

and

loop

stabilization.

Its

Fault

condition

protection

includes

cycle-by-cycle current limiting and thermal

shutdown. In shutdown mode the regulator draws

23µA of supply current. The Programmable soft-

start minimizes the inrush supply current and the

output overshoot at initial startup.

The MP2358 requires a minimum number of

readily available standard external components.
