Device Overview

Summary

The MIC23060 is a highly efficient power management IC integrating a high frequency DC/DC converter with HyperLight Load® mode and a low input voltage capable LDO. The MIC23060 offers two output voltages at very high efficiency on both outputs while maintaining a low total system cost.The MIC23060 also provides sequencing of the two outputs in every potential combination of turn-on and turn-off sequencing by connecting two pins either high or low, and using a single GPIO to enable and disable the device. The LDO is designed both to post regulate from the output of the DC/DC converter for high system efficiency, and/or power directly from the battery. For sequences where the LDO is enabled prior to the DC/DC output, the LDO is first powered by the input voltage (typically the battery source) and then after the DCDC soft start is complete, seamlessly transition LDO input power to draw from the output of the DC/DC converter for higher efficiency operation through post-regulation.The DC/DC converter in the MIC23060 is a HyperLight Load® converter with very high efficiency at light load and at full operating current, maintaining high efficiency across all operating modes in portable electronics.The MIC23060 is a µCap design, operating with small ceramic output capacitors and tiny inductors for stability, reducing required board space and component cost.
