Abstract
A power supply includes a power converter configured to convert an input voltage to a target output DC voltage in response to a feedback signal, the feedback signal having a value. The power supply also includes a regulator coupled to the power converter and configured to generate an output power status signal, which may be in one of two states depending whether an output current from the regulator is above or below a target current over a preset time duration. Further, a control circuit is coupled to the power converter and to the regulator and configured to increment or decrement the value of the feedback signal depending on the state of the power status signal.
