In this paper we study the condition for the dc/dc boost switching regulator operating in discontinuous conduction mode to possibly undergo a period-doubling route to chaos. The essential mathematical tool is the Schwarzian derivative. The result helps determine the form of feedback control scheme for which a period-doubling route to chaos may exist. In particular, any monotonically decreasing control function with a sufficiently large small-signal gain may give rise to a period-doubling cascade in the dc/dc boost switching regulator.
