Beschreibung
The MP28200 is a monolithic power-management unit containing 200mA, high-efficiency, step-down, switching converters. The nanoamp quiescent current provides extremely high efficiency when the load current is down in the μA range. With minimum input voltage as low as 2V, the MP28200 allows the system to operate directly from the battery.
