Device Overview

Summary

The MIC2800 is a high performance power management IC, giving three output voltages with maximum efficiency. Integrating a 2MHz DC/DC converter with an LDO post regulator, the MIC2800 gives two high efficiency outputs with a second, 300mA LDO for maximum flexibility. The MIC2800 features a LowQ® mode, reducing the total current draw while in this mode to less than 30µA. In LowQ® mode, the output noise of the DC to DC converter is 75µVRMS, significantly lower than other converters which use a PFM light load mode that can interfere with sensitive RF circuitry.The DC to DC converter uses small values of L and C to reduce board space but still retains efficiencies over 90% at load currents up to 600mA.The MIC2800 is a μCap design, operating with very small ceramic output capacitors and inductors for stability, reducing required board space and component cost.

    MIC2800 3 output PMIC Evaluation Board ( ADM00864 )

    The MIC2800 Evaluation Board is used to demonstrate the capabilities of MIC2800 PMIC which can deliver 600mA from a DC/DC buck converter and 300mA from each of the two stand-alone LDOs. The board accepts an input voltage from 3.6V to 5.5V and will deliver an output voltage of 1.8V for the DC/DC converter, 1.25V and 3.3V from the LDOs.
