Discharge circuit and method for voltage transition management

A circuit comprising:

• a voltage converter having an output coupled to a voltage rail and configured to generate, at the output of the voltage converter, an output voltage based on a voltage setpoint, wherein the voltage setpoint is indicative of a target output voltage of the voltage converter;
• an output transistor having a current path coupled to the voltage rail;
• a first resistor having a first terminal coupled to a source terminal of the output transistor;
• and
• a control circuit configured to:
• provide the voltage setpoint to the voltage converter;
• cause the output transistor to conduct an output current to or from the voltage rail, wherein a change in the output current is induced by a change in a voltage of a control terminal of the output transistor, and wherein the change in the output current is linear with the change in the voltage of the control terminal;
• and
• cause the output transistor to turn off after the output voltage reaches the target output voltage.
