A multi-phase DC/DC converter having an output voltage and including a
plurality of converter channels. Each converter channel includes a
converter channel input and a converter channel output. Each converter
channel is configured for generating a converter channel current and for
adjusting said converter channel current in response to a control signal
electrically connected to each converter channel input. A control circuit
generates an error signal representative of a comparison of the converter
output voltage to a reference voltage. The control circuit includes a
plurality of control circuit channels, each of which correspond to a
converter channel. Each control circuit channel generates a channel
current signal representative of a corresponding converter channel
current, and generates a differential channel current signal
representative of a comparison of the channel current signal to an
average current signal. The average current signal is representative of
an overall average current for the converter channels. Each control
circuit channel generates a differential error signal representative of a
comparison of the error signal to the differential channel current
signal. Each control circuit channel includes a pulse width modulator
having a ramp input and a control input. The control input is
electrically connected to the differential error signal. The pulse width
modulator generates the control signal based upon the differential error
signal. The control signal is electrically coupled to a corresponding
converter channel input. The control circuit generates the average
current signal.
