Abstract: Disclosed is a voltage regulator circuit configured to selectively operate the voltage regulator circuit in a first mode of operation and a second mode of operation. The voltage regulator can change operation of the voltage regulator circuit between the first mode of operation to the second mode of operation in response to a change in a sensed load condition of the voltage regulator circuit. The voltage regulator can change operation from the second mode of operation to the first mode of operation in response to the sensed load condition changing from the second load condition to the first load condition, but only when the sensed load condition has not changed in a given direction between the first load condition and the second load condition for at least a predetermined period of time T.

Abstract: A power management technique is provided that operates with regard to a dynamic sleep threshold voltage. If a device's battery voltage is greater than the dynamic sleep threshold voltage, a voltage rail for the device is collapsed during a sleep mode for the device. Conversely, if the battery voltage is less than the dynamic sleep threshold voltage, the voltage rail is sourced during the sleep mode for the device.
