Abstract:
A two-terminal rectifier includes a power MOSFET, a body diode, and a Schottky diode coupled between the first terminal and the second terminal. The two-terminal rectifier also has a power management circuit, a capacitor, a control circuit, and a driver circuit coupled between the first terminal and the second terminal. The two-terminal rectifier can be implemented in a two-pin package and can be used in a power converter for CCM operation.

Claim (Index 16):
A power converter having a two-terminal rectifier, the power converter comprising:\n a transformer with a primary winding for receiving a DC input voltage and a secondary winding for providing an output to an output capacitor; a power switch coupled to the primary winding of the transformer; a primary-side controller coupled to the power switch, the primary-side controller being configured to control the power switch for turning on and turning off a current flow in the primary winding, and a two-terminal rectifier coupled to the secondary winding of the transformer and the output capacitor, the two-terminal rectifier configured to adjust a dead time for continuous conduction mode (CCM) operation of the power converter; wherein the two-terminal rectifier comprises:\n a first terminal and a second terminal configured for coupling between the transformer and an output terminal of the power converter; and \n a power management circuit and a capacitor coupled between the first terminal and the second terminal, and being configured to provide operating power to the two-terminal rectifier, such that the two-terminal rectifier is without an additional power supply terminal; wherein the two-terminal rectifier further comprises: a power switch coupled to the first terminal and the second terminal for turning on and off current flow between the first terminal and the second terminal, wherein the power switch comprises a power MOSFET having a source, a drain, a gate, and a body; a body diode formed by a junction between the body and the drain of the power MOSFET or by a junction between the body and the source of the power MOSFET, the body diode being coupled in parallel to the source and drain of the power switch; a Schottky diode coupled to the first terminal and the second terminal; a control circuit coupled to the power management circuit and configured to provide a control signal for controlling an on/off state of the power MOSFET in response to a voltage between the drain and the source of the power switch; and a driver circuit coupled to the control circuit to receive the control signal and to provide a driving signal to the gate of the power MOSFET.
