Abstract:
A converter includes first and second coupled inductors. A first phase includes first high side and low side switches connected to the first inductor. A second phase includes second high side and low side switches connected to the second inductor. In discontinuous conduction mode, the controller determines, in response to the first high side switch being turned on and the second low side switch being turned off, that coupling between the first and second inductors is strong or weak based on whether body diode of the second low side switch will conduct if not prevented from conducting. The controller prevents second low side switch body diode conduction in response to the first high side switch being turned on when the coupling is strong, and does not prevent second low side switch body diode conduction in response to the first high side switch being turned on when the coupling is weak.

Claim (Index 10):
A multiphase DC-DC converter comprising:\n a coupled inductor that includes first and second inductors coupled together; a first phase including first high side and low side switches connected to the first inductor; a second phase including second high side and low side switches connected to the second inductor; a third switch connected across bulk and drain terminals of the second low side switch; a fourth switch connected across bulk and source terminals of the second low side switch; and a controller that:\n drives the first and second high side switches and the first and second low side switches to operate the multiphase DC-DC converter in discontinuous conduction mode; \n turns on the fourth switch in response to the first high side switch being turned on and a voltage at a junction of the second high side and low side switches having a first polarity; and \n turns on the third switch in response to the first high side switch being turned on and the voltage at the junction of the second high side and low side switches having a second polarity that is opposite to the first polarity, \n wherein a body diode of the second low side switch does not conduct.
