MP28115

4A, 1.5MHz Synchronous

Step-Down Converter

The Future of Analog IC Technology

DESCRIPTION

FEATURES

The MP28115 is an internally compensated

1.5MHz fixed frequency PWM synchronous

step-down regulator. MP28115 operates from a

2.7V to 6V input and generates an adjustable

output voltage from 0.8V to 0.9xV_INat up to 4A

load current.

•

4A Output Current

Input Operation Range: 2.7V to 6V

1.5% Output Accuracy

60mΩ Internal Power MOSFET Switches

All Ceramic Capacitor Design

Up to 95% Efficiency

1.5MHz Fixed Switching Frequency

Internal Soft-Start

Frequency Synchronization Input

Power Good Output

Cycle-by-Cycle Current Limiting

Hiccup Short Circuit Protection

Thermal Shutdown

The MP28115 integrates a 60mΩ high-side

switch and a 60mΩ synchronous rectifier for

high efficiency without an external Schottky

diode. With peak current mode control and

internal compensation, the MP28115 based

solution achieves minimum footprint and

component count. Fault condition protection

includes Hiccup short-circuit protection, cycle-

by-cycle current limiting and thermal shutdown.
