A switching mode power converter may include a modulation circuit to
dynamically control a variable switching frequency of the power converter
based on an error voltage of the power converter. The power converter may
also include a control circuit connected to the modulation circuit and
arranged to dynamically limit an inductor current in the power converter
while the switching frequency of the power converter changes. A variable
limit on the inductor current may be based on the error voltage of the
power converter, a load current of the power converter, or information
from a power manager of a system in which the power converter resides. In
some implementations, the power converter may also include a disabling
circuit to control the modulation circuit to disable the variable
switching frequency when a sufficiently large load transient is detected.
