MP2107/MP2107A  
4A, 6V Synchronous  
Step-Down Switching Regulator  
The Future of Analog IC Technology  
DESCRIPTION  
FEATURES  
4A Output Current  
The MP2107 is an internally compensated  
1.5MHz fixed-frequency PWM synchronous  
step-down regulator. MP2107 operates from a  
2.7V to 6V input and generates an output  
voltage as low as 0.8V.  
Input Operation Range: 2.7V to 6V  
60mInternal Power MOSFET Switches  
All Ceramic Capacitor Design  
Up to 95% Efficiency  
1.5MHz Fixed Switching Frequency  
Adjustable Output from 0.8V to 0.9xVIN  
Internal Soft-Start  
Frequency Synchronization Input  
Power Good Output  
Cycle-by-Cycle Current Limiting  
Hiccup Short Circuit Protection  
Thermal Shutdown  
The MP2107 integrates a 80mhigh-side  
switch and a 60msynchronous rectifier for  
high efficiency without an external Schottky  
diode. With peak current mode control and  
internal compensation, the MP2107 based  
solution delivers a very compact footprint with a  
minimum component count.  
The MP2107 is available in a small 3mm x 3mm  
10-pin QFN package and the MP2107A is  
available in an 8-pin SOIC package with an  
exposed pad.  
3mm x 3mm 10-pin QFN (MP2107) and
