MP2131 Overview
The MP2131 is a monolithic step-down, switchmode 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.
