摘要： A method for optimizing operation of a feedback system may include generating a control signal according to a control parameter, regulating an output of the feedback system via the control signal, and monitoring the control parameter. In response to the monitoring indicating that the present value of the control parameter is outside a specific range of values, a first parameter that impacts an operating characteristic of the feedback system may be adjusted until the present value of the control parameter is within the specific range of values. The specific range of values of the control parameter may correspond to a target level of the operating characteristic of the feedback system with respect to the first parameter. One or more additional independent parameters also impacting the operating characteristic of the system may be similarly adjusted to obtain a minimum present value of the control parameter at which the output of the feedback system would be regulated, with the minimum value of the control parameter corresponding to the target level of the operating characteristic of the feedback system with respect to, collectively, the first parameter and the one or more additional independent parameters.

摘要： A new system-level approach to managing the delivery of DC voltage and current. Several system level functions may be enabled without requiring separate ICs to perform those functions. Supervisory functions for a voltage converter may be performed by a central control module or chip that may be coupled to point-of-load voltage converters comprised in digital power management devices (DPMD) through a serial digital bus. The DPMDs may also use the high-speed serial digital bus to provide real-time feedback information to the central control module or chip. Single DPMDs may be combined together in a current sharing configuration in a “plug-and-play” fashion, where the control logic in each DPMD is capable of automatically establishing control loops required a multi-phase supply. Feedback necessary for establishing control may be transmitted across the digital bus coupling the devices. The supervisory functions may be included in each DPMD, which may communicate with each other over a serial digital bus, where the DPMDs singly or together may operate to perform control of their respective POLs, enabling configurations that do not require a central control module.

摘要： Transient processing mechanisms for power converters. Error generation circuitry in a power converter may generate an error signal based on the difference between a power converter output voltage and a reference voltage. Transient detection circuitry may detect whether the error signal exceeds at least a first threshold. If the first threshold is exceeded, timing control logic may generate a low band correction pulse to adjust the power converter output voltage, and thereby adjust the error signal to a level within the first threshold. If the error signal exceeds a second threshold, the timing control logic may generate a high band correction pulse to adjust the power converter output voltage, and thereby adjust the error signal to a level within the second threshold. The timing control logic may initiate a low band blanking period following the low band correction pulse and high band blanking period following the high band correction pulse.

摘要： A current-sense circuit for measuring a load current in a switching power regulator may operate independently of process variation and temperature, and measure bi-directional load currents without requiring high-speed, high-voltage amplifiers for operation. A positive sense voltage may be generated for positive and/or negative values of a switch current conducted by a power switching device in the switching power regulator, by applying a linear transformation to a switch voltage developed across the power switching device according to the switch current. A first sense current may be generated by applying the positive sense voltage across a matching switching device having a same channel length as the power switching device. A second sense current may be generated independently of the switch voltage, and a total sense current that is proportional to the switch current may be calculated by subtracting the second current from the first current. The ratio of the total sense current and the switch current will be independent of process variation and temperature.

摘要： Rather than operating in asynchronous mode during turn-on ramps, a switching power regulator system may be configured to synthesize a digital waveform, which may protect against a pre-bias condition and maintain the desired ramp-up time and rate. The desired turn-on ramp may be generated digitally by counter logic, beginning with an initial value and incrementing at a programmed rate until a digital value equivalent to the desired output voltage is reached. When a pre-bias condition is not present, the output of the digital ramp generator may control a digital-to-analog converter (DAC), which may be configured to generate the reference voltage for the power regulator. To correct for a pre-bias condition, the pre-bias output of the power regulator may be measured prior to turn-on, using an analog-to-digital converter. The digital pre-bias value may be used to control the DAC until the value of the digital waveform generated by the ramp generator reaches the pre-bias value.

摘要： A distributed power management system may include a digital communication bus and a plurality of POL (point-of-load) regulators coupled to the communication bus and configured in a current sharing arrangement in which each POL regulator of the plurality of POL regulators has a respective output stage coupled to a common load and configured to generate a respective output current. Each POL regulator may have a respective phase in the current sharing configuration, and each POL regulator may transmit and receive information over the bus according to a bus communication protocol corresponding to the bus. Each POL regulator may autonomously add and drop its phase as required by the system, by sequentially manipulating a pulse width of a couple of gate signals configured to respectively control a high-side field effect transistor (FET) and low-side FET in the POL regulator's output stage.

摘要： Adaptive thresholding technique for power supplies during margining events. A power supply may include a fault detection mechanism for monitoring an output voltage of the power supply to determine whether the output voltage is greater than a first over-voltage threshold or less than a first under-voltage threshold. If a margining event changes the power supply output voltage, the fault detection mechanism may dynamically change a first over-voltage threshold and a first under-voltage threshold based on the margining event to a second over-voltage threshold and a second under-voltage threshold. Then, during the margining event, the fault detection mechanism may monitor the output voltage of the power supply to determine whether the output voltage is greater than a second over-voltage threshold or less than a second under-voltage threshold. The fault detection mechanism may dynamically change a fault threshold in proportion to the change in the power supply output voltage.
