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 LOWQTM mode, reducing the total current draw while in this mode to less than 30A. In LOWQTM mode, the output noise of the DC to DC converter is 75VRMS, 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.
