MP28114  
Ultra-small  
1.7MHz, 600mA, Low-Voltage  
Synchronous Step-Down Converter  
The Future of Analog IC Technology  
DESCRIPTION  
FEATURES  
The MP28114 is a 1.7MHz constant frequency,  
current mode, ultra-small PWM step-down  
converter. The device integrates a main switch  
and a synchronous rectifier for high efficiency  
and eliminates the needs for an external  
schottky diode. It is ideal for powering portable  
equipment that runs from a single cell Lithium-  
Ion (Li+) battery. The MP28114 can supply  
600mA of load current from a 2.5V to 6V input  
voltage. The output voltage for the MP28114DG  
can be regulated as low as 0.6V, while the  
output voltages of the MP28114DG-1.5,  
MP28114G-1.8, and MP28114DG-3.3 are fixed  
at 1.5V, 1.8V, and 3.3V, respectively. The  
MP28114 can also run at 100% duty cycle for  
low dropout applications. The MP28114 is  
available in an ultra-small 2x2mm QFN package.
