1. Control circuitry configured to control a power converter in accordance with a control variable, comprising:
a first control mechanism configured to generate a first intermediate control variable based on a first physical quantity associated with the power converter;
a second control mechanism configured to generate a second intermediate control variable based on a second physical quantity associated with the power converter;
a selector configured to select the control variable from the first intermediate control variable and the second intermediate control variable; and
a shared feedback memory element configured to feed back the control variable to inputs of the first control mechanism and the second control mechanism, such that:
the first control mechanism generates the first intermediate control variable based on the first physical quantity and the control variable; and
the second control mechanism generates the second intermediate control variable based on the second physical quantity and the control variable.
