MP2127  
2.7-6V Input, 2A, 1.2MHz  
Synchronous Step-Down Converter  
The Future of Analog IC Technology  
DESCRIPTION  
FEATURES  
Output Adjustable from 0.8V to VIN  
Up to 95% Efficiency  
100% Duty Cycle for Low Dropout  
Applications  
Power Good Indicator Output  
1.2MHz Fixed Switching Frequency  
Stable with Low ESR Output Ceramic  
Capacitors  
Thermal Shutdown  
Cycle-by-Cycle Over Current Protection  
Short circuit protection  
2.7V-6V Input Operation Range  
Available in 6-pin 3x3mm QFN  
The MP2127 is a fully integrated, internally  
compensated 1.2MHz fixed frequency PWM  
step-down converter. It is ideal for powering  
portable equipment that runs from a single cell  
Lithium-Ion (Li+) Battery, with an input range  
from 2.7V to 6V. The MP2127 can provide up to  
2A of load current with output voltage as low as  
0.8V. It can also operate at 100% duty cycle for  
low dropout applications. With peak current  
mode control and internal compensation, the  
MP2127 is stable with ceramic capacitors and  
small inductors. Fault condition protection  
includes cycle-by-cycle current limiting and  
thermal shutdown.  
APPLICATIONS  
MP2127 is available in the small 6-pin  
3mmx3mm QFN package.  
Smart Phones, PDA’s  
DVD+/-RW Drives  
Digital Cameras
