Abstract: A system includes a first power stage circuit having a first PWM input, a first voltage input and a first power output. The first power stage circuit is configured to provide a first current at the first power output responsive to a PWM signal at the first PWM input, and configured to receive a voltage at the first voltage input. The system includes a second power stage circuit having a second PWM input, a second voltage input and a second power output. The second voltage input is coupled to the first voltage input, and the second power stage circuit is configured to provide a second current at the second power output responsive to the PWM signal at the second PWM input. The second power stage circuit is configured to receive the voltage at the second voltage input, the voltage representing an average of the first current and the second current.

Abstract: A multiphase controller includes an integrator enable terminal, a pulse width modulator, an error integrator, an open drain driver, and an integrator enable circuit. The integrator enable terminal is adapted to be coupled to the integrator enable terminal of a different instance of the multiphase controller. The pulse width modulator is configured to modulate a power stage. The error integrator is configured to control the pulse width modulator. The open drain driver is coupled to the integrator enable circuit. The integrator enable circuit is coupled to the pulse width modulator, the error integrator, the open drain driver, and the integrator enable terminal. The integrator enable circuit is configured to activate the open drain driver responsive to generation of a power stage control pulse by the pulse width modulator, and activate the error integrator responsive to a logic low signal at the integrator enable terminal.
