Abstract
A switching regulator sources a power rail and includes a top side or input rail side switch, a bottom side or ground side switch, and an inductor. When the switching regulator is disabled or generally turned off, a bottom side transistor in the bottom side switch is pulsed on and off, or held on, to drain or bleed the power rail to ground. When the bottom side transistor is off and if there is a voltage across the inductor from the power rail at a switching node, current flows through a body diode of the top side switch to the input rail of the switching regulator.
