Status: In Production
The MIC2811/21 are high performance power management ICs, supporting four output voltage rails with maximum efficiency. The four rails are generated by a single 600mA DC/DC converter and three 300mA LDOs. LDO1 and LDO2 are capable of operating at a low input voltage down to 1.65V useful for post regulating the output voltage of the DC-DC converter. The MIC2811 supports the use of a bypass cap for improved noise performance on LDO1 and LDO2 while the MIC2821 offers a separate enable pin for LDO3.Featuring an operating frequency of 2MHz, the DC to DC converter uses small values of L and C to reduce board space but still retains operating efficiencies up to 86% at load currents up to 600mA.The MIC2811/21 feature a µCap design, operating with very small ceramic output capacitors and inductors for stability, reducing required board space and component cost.
