MP2326

19V, 4A, 40µA I_Q, High-Efficiency

Constant-On-Time (COT) Step-Down

Converter in a 2mmx3mm QFN Package

The Future of Analog IC Technology

DESCRIPTION

FEATURES

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.



3.9V to 19V Operating Input Range

4A Output Current

40μA Quiescent Current

Output Adjustable from 0.6V

90mΩ/30mΩ High Side/Low Side R_DS(ON)for

Internal Power MOSFETs



Power Good Indicator

Programmable Soft-Start Time

Forced PWM or Auto PFM/PWM Mode

Selectable

With constant-on-time (COT) control, the

MP2326 provides very fast transient response,

easy loop design, and very tight output regulation.



Programmable Switching Frequency

Thermal Shutdown

Short-Circuit Protection: Hiccup Mode

Available in

Package

QFN-14 (2mmx3mm)

Full protection features include SCP, OCP, UVP,

and thermal shutdown.

APPLICATIONS

The MP2326 requires a minimal number of

readily available, standard, external components

with a space saving 2mmx3mm 14-pin QFN

package.



Tablet PCs

Solid State Drives

Gaming
