Abstract
Apparatus and methods for providing an ultra-low power voltage converter are provided. In an example, a method can include receiving an ultra-low power command at a voltage regulator circuit from a load, disabling charge transfer of a regulator of the regulator circuit during an ultra-low power mode of operation in response to a first state of the ultra-low power command, detecting a change in the low power command or in a timeout signal, receiving an indication that the output voltage of the regulator is below a low voltage threshold in response to the change, discharging the output voltage of the regulator for a reset interval in response to the indication, and enabling charge transfer of the regulator after discharging the output voltage.
