  • Methods and apparatus for open-loop enhanced control of power supply transients
    Patent number: 6791302
    Abstract: 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.
