MP28210 Overview
The MP28210 is a monolithic power management unit containing a 1A, highefficiency, step-down, switching converter. The nA quiescent current provides extremely high efficiency when the load current is within the µA range. With a minimum input voltage as low as 2V, the MP28210 allows the system to operate directly from the battery.
