Abstract: A device includes an amplifier having inverting and non-inverting inputs and an output. The device includes a capacitor coupled to a first node and to ground, a resistor coupled to the first node and the amplifier output, and a first switch coupled to the first node and a current sink, which is coupled to ground. The device includes AND gate having inputs and an output coupled to control terminal of first switch. The device includes a first comparator having non-inverting and inverting inputs and an output coupled to an AND gate input; a second comparator having a non-inverting input coupled to the amplifier output, an inverting input coupled to a transistor stack, and an output coupled to an AND gate input; and a second switch coupled to the transistor stack and to a current source, the second switch having a control terminal coupled to the first comparator output.

Abstract: A switching regulator includes a first transistor having a control input and the first transistor is coupled to an input voltage terminal. The regulator includes a second transistor having a control input. The second transistor is coupled to the first transistor at a switch terminal and to a ground terminal. The regulator also includes a controller coupled to the control inputs of the first and second transistor. The controller configured is configured to cause both the first and second transistors to be off concurrently during each of multiple switching cycles for an adaptive high impedance state. The length of time of the adaptive high impedance state is inversely related to current output by the switching regulator.
