The MIC23050 is a 500mA 4MHz switching regulator with HyperLight Load® mode. The MIC23050 is highly efficient throughout the load range and only draws 20μA of quiescent current. The MIC23050 operates from a 2.7V to 5.5V input and features internal power MOSFETs that can supply up to 500mA of output current. It can operate with a maximumduty cycle of 90%.
N/A
The MIC23050 evaluation board requires an input power source that is able to deliver greater than 650mA at 2.7V. The output load can either be an active or passive source.
