This board enables the evaluation of the MIC23153, a fully integrated 2A, 4MHz switching regulator featuring HyperLight Load™ mode, Power Good output indicator, and programmable soft-start. The MIC23153 is highly efficient throughout the entire output current range, drawing just 23μA of quiescent current in operation.

This board needs a single 10W bench power source adjustable from 2.7V to 5.5V. The loads can either be active (electronic load) or passive (resistor) with the capability to dissipate 7W. It is ideal to have an oscilloscope available to view the circuit waveforms, but not essential. For the simplest tests, two Voltage meters are required to measure input and output voltage. For efficiency measurements, two Voltage meters and two Ammeters are required to prevent errors due to measurement inaccuracies.
