Claim 8:
9. A multiphase controller, comprising:
an integrator enable terminal adapted to be coupled to an integrator enable terminal of a different multiphase controller;
a pulse width modulator configured to modulate a power stage;
an error integrator configured to control the pulse width modulator;
an open drain driver coupled to the integrator enable terminal of the multiphase controller; and
an integrator enable circuit coupled to the pulse width modulator, the error integrator, the open drain driver, and the integrator enable terminal, and 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.
