MP2131  
High Efficiency, 4 A, 5.5 V, 1.2 MHz  
Synchronous Step-Down Converter  
The Future of Analog IC Technology  
DESCRIPTION  
FEATURES  
The MP2131 is a monolithic step-down, switch-  
mode converter with built-in internal power  
MOSFETs. It achieves a 4 A continuous output  
current from a 2.7 V to 5.5 V input voltage with  
excellent load and line regulation. The MP2131  
is ideal for powering portable equipment that  
run from a single cell lithium-ion (Li+) battery.  
The output voltage is regulated as low as 0.6 V.
