MP2388

1A, 21V, 2MHz, High-Efficiency,

Synchronous, Step-Down Converter

in Ultra-Thin QFN Package

DESCRIPTION

FEATURES

The MP2388 is a high-frequency, synchronous,

rectified, step-down, switch-mode converter

with built-in, internal power MOSFETs. It offers

a very compact solution that achieves 1A of

continuous output current over a wide input

supply range with excellent load and line

regulation. Current mode operation provides

fast transient response and eases loop

stabilization.

•

Wide 4.5V to 21V Operating Input Range

1A Load Current

110mΩ/50mΩ Low R_DS(ON)Internal Power

MOSFETs

Low Quiescent Current

High-Efficiency Synchronous Mode

Operation

Fixed 2MHz Switching Frequency

AAM Power Save Mode

Internal Soft Start

Over-Current Protection (OCP) and Hiccup

Thermal Shutdown

Output Adjustable from 0.8V

Available in a QFN-8 (1.5mmx2.5mm)

Package

•

Full protection features include over-current

protection (OCP) and thermal shutdown.

The MP2388 requires a minimum number of

readily

available,

standard,

external

components and is available in a space-saving

QFN-8 (1.5mmx2.5mm) package.

APPLICATIONS

•

Notebook Systems and I/O Power

Digital Set-Top Boxes

Flat-Panel Televisions and Monitors
