Power supply and emulated current mode to control generation of an output voltage

A method comprising:

• obtaining an output current value representative of a magnitude of an output current supplied by an output voltage of a power converter to power a load;
• storing the output current value;
• producing a first offset reference signal, the output current value being offset by the first offset reference signal;
• and
• controlling generation of the output voltage of the power converter as a function of the offset output current value with respect to a threshold signal, the threshold signal generated based on an error voltage, the error voltage being a difference between a magnitude of the output voltage and a target reference voltage;
• producing a second offset reference signal;
• and
• via a summer, summing the error voltage and the second offset reference signal to produce an offset error voltage.

An apparatus comprising:
