MP28128  
2.5A, 1.5MHz Synchronous  
Step-Down Converter  
The Future of Analog IC Technology  
DESCRIPTION  
FEATURES  
The MP28128 is a 1.5MHz fixed frequency  
PWM synchronous step-down regulator with  
internal compensation. MP28128 operates from  
a 2.7V to 6V input and generates an adjustable  
output voltage from 0.8V to 0.9xVIN at up to  
2.5A load current.  
2.5A Output Current  
Input Operation Range: 2.7V to 6V  
1.5% Output Accuracy  
Internal Power MOSFET Switches  
All Ceramic Capacitor Design  
1.5MHz Fixed Switching Frequency  
Internal Soft-Start  
Frequency Synchronization Input  
Power Good Output  
The MP28128 integrates an 80mhigh-side  
switch and a 60msynchronous rectifier for  
high efficiency without an external Schottky  
diode. With peak current mode control and  
internal compensation, the MP28128 based  
solution delivers a very compact footprint with a  
minimum component count. Fault condition

APPLICATIONS  
protection, cycle-by-cycle current limiting and  
thermal shutdown. Other features include  
frequency synchronization input, internal soft-  
start and power good output.
