MP2227

24V, 3A, 1.3MHz Synchronous

Step-Down Converter

The Future of Analog IC Technology

DESCRIPTION

FEATURES



3A Output Current

The MP2227 is an internally compensated

1.3MHz fixed frequency PWM synchronous

step-down regulator. MP2227 operates from a

3V to 24V input and generates an adjustable

output voltage from 0.8V to 0.9xV_INat up to 3A

load current.

Input Supply Range: 3V to 24V

160mΩ high-side, 80mΩ low-side Internal

Power MOSFET Switches

All Ceramic Output Capacitor Design

Up to 95% Efficiency

1.3MHz Fixed Switching Frequency

Adjustable Output from 0.8V to 0.9xV_IN

Internal LDO for V_CCsupply

1MHz to 2MHz Frequency Synchronization

POK



The MP2227 integrates a 160mΩ high-side

switch and an 80mΩ synchronous rectifier for

high efficiency without an external Schottky

diode. With peak current mode control and

internal compensation, it is stable with an

output ceramic capacitor and a small inductor.

Fault protection includes hiccup short-circuit

protection, cycle-by-cycle current limiting and

thermal shutdown. Other features include

frequency synchronization and soft-start.

Thermal Shutdown

Cycle-by-Cycle Current Limiting

Hiccup Short Circuit Protection

10-lead, 3mm x 3mm QFN Package

APPLICATIONS

The MP2227 is available in a small 3mm x 3mm

10-lead QFN package.
