Abstract: A multi-phase power converter with current matching is provided. The apparatus may include a control circuit to control a first phase of a power converter having a plurality of phases, and a phase matching circuit. The phase matching circuit may remove a DC component from an output ripple voltage of the converter, detect when respective ones of the plurality of phases begins generating its respective phase current and output a phase detector signal, extract a signal proportional to the first phase current and a signal proportional to either the remaining or total phase currents, output first and second voltages respectively proportional to the average of the first phase current and the remaining or total phase current, and output a corrective signal based on the difference between the first and second voltage. The control circuit may control the first phase based on the corrective signal.

Abstract: A control circuit includes a discharge circuit, a control logic, and an output. The output is communicatively coupled to a control terminal of a power transistor. The control circuit further includes an input communicatively coupled to an input of the transistor. In a discharge mode of operation, the control logic is configured to provide a control terminal voltage to the control terminal of the power transistor via the output. The control terminal voltage is configured to operate the power transistor linearly to dissipate energy stored in a capacitance connected to an input of the power transistor/In the discharge mode, the discharge circuit is configured to receive a discharge current from an output of the power transistor, and to dissipate remaining energy undissipated by the power transistor.
