1. An apparatus comprising:
a power supply controller operative to:
produce an output voltage via supply of output current from at least one power supply phase of a power supply to power a load;
generate a switching period adjustment signal based on an error voltage indicating a difference between the output voltage and a setpoint voltage;
derive a current control signal from the error voltage; and
generate a pulse width modulation signal of a first power supply phase based on the switching period adjustment signal and the current control signal.
