AUXILIARY TURN-ON MECHANISMS FOR REDUCING CONDUCTION LOSS IN BODY-DIODE OF LOW SIDE MOSFET OF COUPLED-INDUCTOR DC-DC CONVERTER

摘要

An embodiment of a power-supply controller includes first and second circuits. The first circuit is operable to cause a first current to flow through a first phase of a power supply. And the second circuit is operable to cause the second phase of the power supply to operate in a reduced-power-dissipation mode for at least a portion of a time period during which a second current magnetically induced by the first current flows through the second phase.
