DESCRIPTION

The EV2276-D-00A is an evaluation board for

the MP2276, a high efficiency, monolithic,

synchronous step-down converter.

The EV board can deliver 8A continuous load

current over a wide operating input range. High

efficiency can be achieved over a wide output

current load range.

The MP2276 adopts internally compensated

constant-on-time

(COT)

control

mode

that

provides fast transient response and eases loop

stabilization.

This EV board can be turned on or off via a

remote ON/OFF input (EN) that is referenced to

ground. This input is compatible with popular logic

devices.
