1. A method comprising:
receiving, by a power delivery (PD) controller from a voltage sensing circuit, a first sensed voltage indicating an input voltage, while the PD controller is producing a first control signal for a voltage converter circuit;
in response to determining that the first sensed voltage passes a threshold voltage, starting, by the PD controller, a timer, wherein the threshold voltage is a first threshold, a second threshold, or a third threshold;
during a time period of the timer, producing, by the PD controller, the first control signal;
during the time period of the timer, receiving, by the PD controller, a second sensed voltage from the voltage sensing circuit; and
after expiration of the timer, producing, by the PD controller, a second control signal for the voltage converter circuit based on the second sensed voltage.
