摘要： Disclosed is a digital current sharing structure and method in which a plurality of regulators are configured to share the load current. Current share circuits in each of the regulators are configured to measure and compare the average current provided by that particular regulator with the overall average current provided by all the regulators. Each of the current share circuits then provides an output so that the output of each regulator is adjusted to provide the same amount of current to the load. Digital processing with both analog and digital averaging are disclosed. Also disclosed is a programmable hysteresis technique to eliminate relatively trivial adjustments.

摘要： Disclosed is a multi-phase pulse width modulated voltage regulator and method in which transient voltage excursions or deviations that exceed the load line voltage by more than a pre-determined amount are detected by an ATR circuit and a correction signal is applied. The correction signal is in the form of asynchronous pulses and the number of such pulses is a function of the magnitude of the voltage excursion as determined by the number of thresholds that are exceeded. Also disclosed is an adaptive voltage positioning (AVP) circuit and method for early detection of a transient event by sensing voltage changes at the load and adjusting the target voltage with pre-determined current values prior to the time that ATR event changes in the current at the load are detected. The AVP load line is pre-positioned for more precise current control. Also disclosed is an adaptive filter with adjustable frequency characteristics in response to an ATR event. Also disclosed is a pulse limiting circuit. Also disclosed is a tri-state implementation. Response to transient events is further improved with an external ATR circuit coupled to the load.

摘要： A system is provided for supplying current to a dynamic load subject to transient current requirements. A sense unit coupled to the dynamic load is configured to sense the rate of change of supply current required by the dynamic load during a transient event. A current source coupled to the sense unit is configured to supply a current pulse to the dynamic load in response to the sense unit determining that the rate of change of supply current (di/dt) exceeds a predetermined threshold. The current pulse preferably has a shape characterized by a first region and a second region subsequent to the second region, wherein the first region includes a first boost current which exceeds the transient current requirement, and wherein the second region includes a second boost current which is less than the transient current requirement. More generally, a wideband transient suppression system is provided for controlling a wide spectrum of transients. The wideband system includes a primary regulator configured to compensate for low frequency transients, and a secondary regulator configured to provide short-term compensation current to the dynamic load until the relatively slow primary regulator can accommodate the transient event. The secondary regulator includes two major functional blocks: a close-loop voltage-sensing compensation circuit configured to compensate for transients falling within a mid-range frequency range, and an open-loop di/dt-sensing compensation circuit configured to compensate for transients falling within a high-frequency range.

摘要： A wideband voltage regulator is configured to provide suppression of fast transients, which can include a boosting circuit and a sensing circuit. The boosting circuit can be suitably configured to boost the voltage regulator response, while the sensing circuit can determine when such a boost may be desired. Accordingly, the response of the voltage regulator can be accelerated to a fast load transient beyond the closed loop bandwidth limited response or the slew rate limited response of the voltage regulator. An exemplary voltage regulator can be configured with an active sensing circuit comprising a sensing amplifier with switch control outputs, and a boosting circuit comprising N stored charge sources, e.g.; boost capacitors, and (3N−1) switches that are configured to accelerate the voltage regulators response to a fast load transient beyond the closed loop bandwidth limited or slew rate limited response of the voltage regulator.
