MIC2800-A4SYML

Digital Power Management IC 2MHz, 600mA DC-DC w/Dual 300mA/300mA Low VIN LDOs

General Description

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.
