    摘要: Disclosed is a digitally controlled multi-phase voltage regulator system providing regulated power to electronic components that have variable power requirements. Power is supplied by one or more power integrated circuits (IC) each having a high side power switch controlled by pulse width modulated signals and a low side power switch. The power IC senses voltage at the load and has an on-chip current mirror for generating a current that is a ratio of current delivered to the load. The power IC also has current limiting and on-chip temperature sensing components. The voltage and current information is digitized and provided to a control integrated circuit (IC). The control IC receives this digitized information as well as user provided parameters and, in the regulation mode of operation, provides digitized pulse width modulated control signals to the power IC. In an active transient response mode of operation, the control IC provides signals to turn either the high side switches or low side switches ON. Fault detection circuitry identifies over voltage, under voltage, and excessive temperatures. All communications between the control IC and the power IC are digital providing high bandwidth, optimal control frequency response, noise immunity and efficient active transient response.

    摘要: A control circuitry can be configured to receive an error signal indicating a difference between an output voltage of the power supply and a desired setpoint for the output voltage. According to one configuration, depending on the error signal, the control circuitry initiates switching between operating the control circuitry in a pulse width modulation mode and operating the control circuitry in a pulse frequency modulation mode to produce an output voltage. Operation of the control circuitry in the pulse frequency modulation mode during a transient condition, such as when a dynamic load instantaneously requires a different amount of current, enables the power supply to satisfy current consumption by the dynamic load. Subsequent to the transient condition, the control circuitry switches back to operation in the pulse width modulation mode.

    摘要: According to example configurations herein, a leadframe includes a first conductive strip, a second conductive strip, and a third conductive strip disposed substantially adjacent and substantially parallel to each other. A semiconductor chip substrate includes a first array of switch circuits disposed adjacent and parallel to a second array of switch circuits. Source nodes in switch circuits of the first array are disposed substantially adjacent and substantially parallel to source nodes in switch circuits of the second array. When the semiconductor chip and the leadframe device are combined to form a circuit package, a connectivity interface between the semiconductor chip and conductive strips in the circuit package couples each of the source nodes in switch circuits of the first array and each of the multiple source nodes in switch circuits of the second array to a common conductive strip in the leadframe device.

    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: According to example configurations as described herein, a power supply system includes a unique circuit including an analog summer circuit, an analog-to-digital converter, and a digital controller. An output voltage feedback control loop of the power supply system feeds back the output voltage to the analog summer circuit. The analog summer circuit generates an analog error voltage signal based on: i) the output voltage received from the output voltage feedback loop, ii) an analog reference voltage signal, and iii) an analog reference voltage adjustment signal. The analog reference voltage adjustment signal varies depending on a magnitude of current provided by the output voltage to the dynamic load. Accordingly, the analog summer circuit can be configured to support adaptive voltage positioning. The analog-to-digital converter converts the analog error voltage signal into a digital error voltage signal. A controller generates output voltage control signal(s) based on the digital error voltage signal.
