MP2338

High-Efficiency, 28V, 3A, 450kHz,

Synchronous Step-Down Converter

In SOT583 Package

DESCRIPTION

FEATURES



Wide 4.5V to 28V Operating Input Range

Wide 0.5V to 16V V_OUT

±1.5% Internal Reference Accuracy Over-

Temperature

115mΩ/55mΩ Low R_DS(ON)Internal Power

MOSFETs

The MP2338 is a fully integrated, high-

frequency, synchronous, rectified, step-down

switch-mode converter with internal power

MOSFETs. It offers a very compact solution to

achieve 3A of continuous output current across

a wide input range, with excellent load and line

regulation. The MP2338 has synchronous

mode operation for high efficiency across the

wide output current load range.



160µA Quiescent Current

>90% Efficiency for 24V to 5V/3A Condition

Power Save Mode at Light Load

Fast Load Transient Response

450kHz Switching Frequency

Constant-on-time (COT) control provides very

fast transient response and easy loop design,

as well as tight output regulation.

t_ONExtension to Improve Dropout

Configurable Soft-Start Time

Power Good Indication

Over-Current Protection (OCP) with Hiccup

Mode

Full protection features include short-circuit

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

under-voltage protection (UVP), and thermal

shutdown.



Thermal Shutdown Protection

The MP2338 requires a minimal number of

readily available, standard external components.

It is available in a space-saving SOT583

package.
