MP2392

High-Efficiency, 2A, 24V, 650kHz

Synchronous, Step-Down Converter

with PG and Soft Start In SOT583

DESCRIPTION

FEATURES

The MP2392 is a fully integrated, high-

frequency, synchronous, rectified, step-down,

switch-mode converter with internal power

MOSFETs. The MP2392 offers a very compact

solution that achieves 2A of continuous output

current with excellent load and line regulation

over a wide input range. The MP2392 uses

synchronous mode operation for higher

efficiency over the output current-load range.



Wide 4.2V to 24V Operating Input Range

110mΩ/45mΩ Low R_DS(ON)Internal Power

MOSFETs

200µA Low I_Q

High-Efficiency Synchronous Mode

Operation

Power-Save Mode (PSM) at Light Load

Fast Load Transient Response

650kHz Switching Frequency

Programmable Soft-Start Time

Power Good (PG) Indication

Output Over-Voltage Protection (OVP)

Over-Current Protection (OCP) and Hiccup

Pre-Bias Start-Up



Constant-on-time (COT) control operation

provides very fast transient response, easy loop

design, and very tight output regulation.

Full protection features include short-circuit

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

under-voltage protection (UVP), and thermal

shutdown.

Thermal Shutdown

Available in a SOT583 (1.6mmx2.1mm)

Package

The MP2392 requires a minimal number of

APPLICATIONS

components and is available in a space-saving

SOT583 package.



Game Consoles

Digital Set-Top Boxes

Flat-Panel Televisions and Monitors
