1. A circuit comprising:
a loop controller having current phase inputs, a feedback input, a control loop output and a transient event output, the feedback input adapted to be coupled to an output terminal of a multi-phase power stage;
a pulse width modulation (PWM) circuit having a blanking input, a control input and a PWM output, the control input coupled to the control loop output; and
a phase management circuit having a transient detect input, a PWM input, a blanking output and phase outputs, the transient detect input coupled to the transient event output, the PWM input coupled to the PWM output, the blanking output coupled to the blanking input, and each of the phase outputs adapted to be coupled to a respective phase of the multi-phase power stage, the phase management circuit configured to provide a blanking control signal at the blanking output representative of a variable blanking time.
