A technique for addressing a low line voltage condition in an information
handling system includes determining whether a magnitude of an input
voltage of a power supply unit (PSU) is below a first threshold for at
least a first time period. The technique also includes adjusting, based
on the determining, a magnitude of a reference voltage of the PSU to
track a magnitude of an output voltage of the PSU when the input voltage
is below the first threshold for at least the first time period.
