MP2393

24V, 3A, 650kHz, Synchronous

Step-Down Converter with PG, SS,

in 1.6x2.1mm SOT583 Package

DESCRIPTION

FEATURES

The MP2393 is a fully integrated, high-

frequency, synchronous, rectified, step-down,

switch-mode converter with internal power

MOSFETs. The MP2393 offers a very compact

solution that achieves 3A of continuous output

current with excellent load and line regulation

over a wide input range. The MP2393 uses

synchronous mode operation for higher

efficiency over the output current load range.



Wide 4.2V to 24V Operating Input Range

75mΩ/40mΩ 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 (SS) Time

Power Good (PG) Indication

Over-Current Protection (OCP) and Hiccup

Pre-Bias Start-Up

Thermal Shutdown

Available in a SOT583 (1.6mmx2.1mm)

Package



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.
