Abstract
In an embodiment, a method includes: providing a voltage setpoint to a voltage converter; generating an output voltage at a voltage rail with the voltage converter based on the voltage setpoint; when the voltage setpoint is transitioning from a first voltage setpoint to a second voltage setpoint that has a lower magnitude than the first voltage setpoint, providing a first constant current to a first node coupled to a control terminal of an output transistor to turn on the output transistor, where the output transistor includes a source terminal coupled to a first terminal of a first resistor, and where a current path of the output transistor is coupled to the voltage rail; and turning off the output transistor after the output voltage reaches the target output voltage corresponding to the second voltage setpoint.
