MIC2800

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 30A. In LOWQ™ 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 of MIC2800 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 Cap design, operating with very small ceramic output capacitors and inductors for stability, reducing required board space and component cost and it is available in fixed output voltages in the 16-pin 3mm x 3mm MLF® leadless package.
