Abstract: A multiphase converter provides an output voltage to a load. The multiphase converter receives a load event signal from the load and turns ON at a same time the phases of the multiphase converter to increase the output voltage in response to the load event signal indicating that a load current drawn by the load from the multiphase converter is about to increase. The multiphase converter increases an impedance of low-side switches of the multiphase converter in response to the load event signal indicating that the load current is about to decrease.

Abstract: A power module has a substrate, a magnetic component disposed on the substrate, a plurality of power integrated circuits (ICs), and a heat spreader. The heat spreader and at least a part of the plurality of power ICs are disposed on a top surface of the substrate. The heat spreader is fixed on the substrate through a structural adhesive, covering top surfaces of the part of the plurality of power ICs on the top surface of the substrate, and is in contact with the top surfaces of the part of the plurality of power ICs on the top surface of the substrate through a thermal conductive adhesive. A difference between a height measured from a topmost surface of the magnetic component to the top surface of the substrate and a height measured from a topmost surface of the heat spreader to the top surface of the substrate is within 300 um.

Abstract: A voltage regulator has a switching circuit and a control circuit. The switching circuit provides an output voltage and an output current. The control circuit provides a switching control signal to the switching circuit to adjust the output voltage, such that the output voltage decreases with a first slope as the output current increases when the output current is less than a predetermined current, the output voltage decreases with a second slope as the output current increases when the output current is larger than the predetermined current.

Abstract: A resonant converter has a primary resonant tank circuit and a secondary resonant tank circuit. An inverter circuit converts an input DC voltage received by the resonant converter at an input voltage node to a pulsating signal that is fed to the primary resonant tank circuit to generate a resonant tank current that flows through a primary winding of a transformer. The resonant tank current induces current in a secondary winding of the transformer. The induced current is rectified by a rectifier and the rectified signal is filtered to generate an output DC voltage at an output voltage node. The secondary resonant tank circuit is disposed between the secondary winding of the transformer and the output voltage node, and a tank node of the secondary resonant tank is connected to the primary resonant tank circuit through the inverter circuit.
