DESCRIPTION

The MP2316 is a fully-integrated, high efficiency,

synchronous, step-down switch-mode converter,

featuring only 40μA quiescent current. This very

compact device achieves 3A continuous output

current over a wide input supply range with

excellent load and line regulation, and can

operate with high efficiency over a wide output

current load range. It’s optimized for battery-

operated applications and applications requiring

high light load efficiency.

With Constant On-Time control, the MP2316

provides very fast transient response, easy loop

design as well as very tight output regulation.

Full protection features include SCP, OCP, UVP,

and thermal shutdown.

The MP2316 requires a minimal number of

readily available standard external components

with a space saving 2mmx3mm 14-pin QFN

package.
