Abstract
A power converter circuit can be operated in a constant-current mode when a monitored output current exceeds a specified over-current threshold. A value representing an output voltage of the power converter circuit can be compared to a soft-start voltage reference value. The soft-start voltage reference value can be set (or reset) to a value representing the output voltage of the power converter when the difference between the soft-start voltage reference value and the value representing the output voltage of the power converter is greater than a specified threshold. The output voltage of the power converter can be regulated using the soft-start voltage reference value as a target voltage including ramping the soft-start voltage reference value at specified rate to maintain the soft-start voltage reference value within a specified range of a specified regulated output voltage value, such as to constrain a slew rate of the regulated output voltage.
