MP2125  
Dual 1.5A, 1.2MHz  
Synchronous Step-Down Converter  
The Future of Analog IC Technology  
DESCRIPTION  
FEATURES  
2.7V-6V Input Operation Range  
Each Output Adjustable from 0.8V to VIN  
1uA Shutdown Current  
Up to 92% Efficiency  
100% Duty Cycle for Low Dropout  
Applications  
The MP2125 is a fully integrated dual PWM  
step-down converter with built-in internal power  
MOSFETs. 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 MP2125 can provide up to 1.5A of  
load current with output voltage as low as 0.8V  
for each output. It can also operate at 100%  
duty cycle for low dropout applications.  
Fixed 1.2MHz Frequency  
Stable with Low ESR Output Ceramic  
Capacitors  
Cycle-by-Cycle Over Current Protection  
Thermal Shutdown  
Short Circuit Protection  
Available in 14-pin 3mmx4mm QFN  
package  
With peak current mode control and internal  
compensation, the MP2125 is stable with  
ceramic capacitors and small inductors.  
Fault condition protection includes cycle-by-  
cycle current limiting and thermal shutdown.  
APPLICATIONS  
MP2125 is available in the small 14-pin  
3mmx4mm QFN package.
