MP2012  
Low Voltage, 2.7-6V Input,1.5A, 1.2MHz  
Synchronous Step-Down Converter  
The Future of Analog IC Technology  
DESCRIPTION  
FEATURES  
2.7-6V Input Operation Range  
Output Adjustable from 0.8V to VIN  
1μA Max Shutdown Current.  
Up to 95% Efficiency  
100% Duty Cycle for Low Dropout  
Applications  
1.2MHz Fixed Switching Frequency  
Stable with Low ESR Output Ceramic  
Capacitors  
The MP2012 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 MP2012 can provide up to  
1.5A 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  
MP2012 is stable with ceramic capacitors and  
small inductors. Fault condition protection  
includes cycle-by-cycle current limiting and  
thermal shutdown.  
Thermal Shutdown  
Cycle-by-Cycle Over Current Protection  
Short Circuit Protection  
Available in QFN6 (3x3mm)  
MP2012 is available in a small QFN6 (3x3mm)  
package.  
APPLICATIONS  
DVD+/-RW Drives  
Smart Phones  
PDAs  
Digital Cameras  
Portable Instruments
