Classification: CPC H | IPC H

Claim 16:
17. A multiphase converter, comprising:
a first multiphase controller including:
an integrator enable terminal; and
a controller startup terminal;

a power stage including a temperature sense terminal coupled to the control startup terminal of the first multiphase controller;
a second multiphase controller including:
a controller startup terminal coupled to the temperature sense terminal of the power stage;
an integrator enable terminal coupled to the integrator enable terminal of the first multiphase controller;
a pulse width modulator configured to modulate the power stage;
an error integrator configured to control the pulse width modulator;
an open drain driver coupled to the integrator enable terminal of the second 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 of the second multiphase controller, 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 the first multiphase controller generating a logic low signal at the integrator enable terminal of the second multiphase controller.
