DESCRIPTION

The MP2326 is a fully integrated, high-efficiency,

synchronous, step-down, switch-mode converter

with only a 40μA quiescent current. This very

compact device achieves a 4A continuous output

current over a wide input-supply range with

excellent load and line regulation, and it operates

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

(COT)

control,

the

MP2326 provides very fast transient response,

easy loop design, and very tight output regulation.

Full protection features include SCP, OCP, UVP,

and thermal shutdown.

The MP2326 requires a minimal number of

readily available, standard, external components

with a space saving 2mmx3mm 14-pin QFN

package.
