MP2319

3A, 18V, 650kHz, High-Efficiency,

Synchronous, Step-Down Converter

in 8-Pin TSOT23

DESCRIPTION

FEATURES

The MP2319 is

fully-integrated, high-



Wide 4.5V to 18V Operating Input Range

3A Output Current

105mΩ/57mΩ Low R_DS(ON)Internal Power

MOSFETs

Output Adjustable from 0.8V

EN Shutdown Output Discharge

Internal Soft Start

High-Efficiency Synchronous Mode

Operation

frequency, synchronous, rectified, step-down,

switch-mode converter with internal power

MOSFETs. The MP2319 offers a very compact

solution that achieves 3A of continuous output

current with excellent load and line regulation

over a wide input range. The MP2319 has

synchronous mode operation for higher

efficiency over the output current load range.



Constant-on-time control operation provides a

very fast transient response, easy loop design,

and very tight output regulation.



Fixed 650kHz Switching Frequency

EN and Power Good for Power Sequencing

Over-Current Protection (OCP) and Hiccup

Thermal Shutdown

Auto-Retry Over-Voltage Protection (OVP)

Available in a TSOT23-8 Package

Full protection features include short-circuit

protection (SCP), over-current protection (OCP),

under-voltage protection (UVP), over-voltage

protection (OVP), and thermal shutdown.

APPLICATIONS

The MP2319 requires a minimal number of



Security Cameras

Portable Devices, xDSL Devices

Digital Set-Top Boxes

Flat-Panel Televisions and Monitors

General Purposes

readily

available,

standard,

external

components and is available in a space-saving,

8-pin, TSOT23 package.
