摘要： According to example configurations herein, a leadframe includes a connection interface. The connection interface can be configured for attaching an electrical circuit to the leadframe. The leadframe also can include a conductive path. The conductive path in the leadframe provides an electrical connection between a first electrical node of the electrical circuit and a second electrical node of the electrical circuit. Prior to making the connection between the electrical circuit and the leadframe, the first electrical node and the second electrical node can be electrically isolated from each other. Subsequent to making connection of the electrical circuit with the leadframe, the conductive path of the leadframe electrically connects the first electrical node and the second electrical node together. Accordingly, the leadframe provides connectivity between nodes of an electrical circuit in lieu of having to provide such connectivity at, for example, a metal interconnect layer of an integrated circuit device.

摘要： A power supply controller produces a compensation value based at least in part on: an estimated or known output capacitance of the power supply, a specified rate of changing a magnitude of the output voltage as specified by the voltage setting information, and/or a load-line resistance of the power supply. The power supply controller utilizes the compensation value to adjust a magnitude of the output voltage during a voltage transition in which the output voltage is changed from an initial output voltage setting to a target output voltage setting at a pre-specified rate.

摘要： According to example configurations herein, while operating a power supply in a discontinuous power supply mode, a controller initiates activation of a first switch of the power supply to increase a magnitude of current flowing through an inductor. The flow of current through the inductor produces an output voltage for powering a load. The controller estimates a time duration in which to activate a second switch of the power supply to reduce the current flowing through the inductor. The controller uses the estimated time duration as a parameter for controlling the second switch in the power supply. For example, upon or after deactivating the first switch, the controller initiates activation of the second switch for the estimated time duration. Deactivation of the second switch based on the estimated time duration reduces or eliminates a need to employ complex circuitry to physically measure a magnitude of current through the inductor.

摘要： A power supply circuit can be configured to include a first circuit and a second circuit. Each circuit can be substantially identical to each other but provide different functionality depending on how they are configured. For example, each of the first circuit and second circuit can be chips having substantially the same pin layout and internal circuitry. However, the functionality provided by the circuits varies depending on whether a respective circuit is configured as a master or slave. The first circuit is configured as the master and generates multiple phase control signals. The first circuit uses a portion of the multiple phase control signals to control a first set of phases. The first circuit transmits a second portion of the multiple phase control signals to the second circuit configured as a slave. The second circuit is configured to receive and use the second portion of control signals to control a second set of phases.

摘要： According to one configuration, a multi-phase power supply adjusts a number of active phases based at least in part on a peak current supplied to a dynamic load. For example, a controller associated with the multi-phase power supply can monitor or receive a value indicative of a peak magnitude of current delivered by the multi-phase power supply to a dynamic load. The controller initiates comparison of the value to threshold information. Based at least in part on the comparison, the controller adjusts how many phases of the multi-phase power supply are activated to deliver the current delivered to the dynamic load. Thus, one embodiment herein is directed to controlling a multi-phase power supply based at least in part on a measured parameter such as peak current magnitude.

摘要： According to one configuration, a monitor circuit monitors a delivery of power supplied by one or more switch devices to a dynamic load. Based on an amount of power delivered to the load as measured by the monitor circuit, a control circuit produces a voltage control signal. A gate bias voltage generator circuit utilizes the voltage control signal to generate a switch activation voltage or bias voltage. A switch drive circuit uses the switch activation voltage as generated by the bias voltage generator to activate each of the one or more switch devices during a portion of a switching cycle when a respective switch device is in an ON state, and the respective switch device conducts current from a voltage source through the switch device to the load. The control circuit adjusts the voltage control signal to modify a level of the switch activation voltage depending on the dynamic load.

摘要： A control circuit generates an output based on the first signal and the second signal by encoding the output to be a multi-state signal having at least three states. A magnitude of the multi-state signal generated by the controller varies depending on binary states of the first signal and the second signal. The controller utilizes the output (i.e., the multi-state signal) to control a switching circuit. A driver circuit receives the output generated by the control circuit. In one embodiment, the multi-state signal has more than two different logic states. The driver decodes the multi-state signal for generating signals to control switches in the switching circuit. One signal generated by the driver circuit is a pulse width modulation signal; another signal generated by the driver circuit is an enable/disable signal.

摘要： A power supply system includes multiple power converter phases. A controller (e.g., a processor device) monitors energy delivery for each of multiple power converter phases that supply energy to a load. The controller analyzes the energy delivery associated with each of the multiple power converter phases to identify an imbalance of energy delivered by the multiple power converter phases to the load. Based on the analyzing and detection of an imbalance condition, the controller modifies a future order of activating the multiple power converter phases for powering the load. Accordingly, a single phase of a multiphase switching power converter may be prevented from becoming overloaded while delivering energy to power the load.
