MP28127  
1.25A, 5.5V Synchronous  
Step-Down Switching Regulator  
The Future of Analog IC Technology  
DESCRIPTION  
FEATURES  
The MP28127 is an internally compensated  
1.5MHz fixed frequency PWM synchronous  
step-down regulator. MP28127 operates from a  
2.7V to 5.5V input and generates an output  
voltage as low as 0.8V.  
1.25A Output Current  
Input Operation Range: 2.7V to 5.5V  
All Ceramic Capacitor Design  
1.5MHz Fixed Switching Frequency  
Adjustable Output from 0.8V to 0.9xVIN  
Internal Soft-Start  
Frequency Synchronization Input  
Power Good Output  
Thermal Shutdown  
The MP28127 integrates a high-side switch and  
a synchronous rectifier for high efficiency  
without an external Schottky diode. With peak  
current  
mode  
control  
and  
internal  
compensation, the MP28127 based solution  
delivers a very compact footprint with a  
minimum component count.  
Cycle-by-Cycle Current Limiting  
Hiccup Short Circuit Protection  
3mm x 3mm 10-lead QFN Package  
The MP28127 is available in a small 3mm x  
3mm 10-lead QFN package.  
APPLICATIONS  
µP/ASIC/DSP/FPGA Core and I/O Supplies  
Printers and LCD TVs  
Network and Telecom Equipment
