MP2183C

2.5V to 5.5V, 3A, Synchronous,

Step-Down Converter with SS, PG,

and Forced PWM in SOT583 Package

DESCRIPTION

FEATURES

The MP2183C is a monolithic, step-down,

switch-mode converter with built-in internal

power MOSFETs. It achieves 3A of continuous

output current from a 2.5V to 5.5V input voltage

range, with excellent load and line regulation.

The output voltage can be regulated to as low as

0.6V.



Forced PWM Mode Operation

1.2MHz Switching Frequency

EN for Power Sequencing

1% FB Accuracy

Wide 2.5V to 5.5V Operating Input Range

Output Adjustable from 0.6V

Up to 3A Output Current

65mΩ and 35mΩ Internal Power MOSFET

Switches

100% Duty On

Output Discharge

V_OOVP

External Soft Start Control

Short-Circuit Protection with Hiccup Mode

Power Good

A constant-on-time (COT) control scheme

provides fast transient response and eases loop

stabilization. Fault protections include cycle-by-

cycle current limiting and thermal shutdown.



The MP2183C is ideal for a wide range of

applications including high-performance DSPs,

wireless power, portable and mobile devices,

and other low-power systems.

Available in a SOT583 Package

The device requires a minimal number of readily

available, standard external components. It is

available in an ultra-small SOT583 package.

APPLICATIONS



Wireless/Networking Cards

Portable Instruments

Low-Voltage I/O System Power

Multi-Function Printers
