When the main supply is removed, the reg- ulator operates in boost mode and prevents the system from dropping below the minimum operating voltage, dis- charging the storage element at up to 2.5A peak inductor current. The MAX38888 is externally programmable for minimum and maximum voltage of the storage element, such as supercapacitor, minimum system voltage, and maximum charge and discharge currents. The internal DC-DC con- verter requires only a 1H inductor.
