Apparatus and method for regulating a switching circuit of a voltage converter for supplying power to a pulsed load having a known upcoming magnitude. The voltage converter includes a switching circuit receiving a switching signal with duty cycle that is adjusted by a voltage controller. The voltage controller is responsive to a known upcoming cycle phase and a corresponding magnitude of the pulsed load for forward-correcting the duty cycle of the switching signal. In order to compensate for variations in load consumption owing, for example, to varying ambient conditions, circuit aging, battery discharge and other slow changes, or for imprecise foreknowledge thereof, the voltage controller may also monitor an output voltage of the voltage converter during successive cycles and apply feedback correction based on a predicted value of compensation required for the respective phase of a subsequent cycle.
Method for regulating a voltage converter for supplying power to a pulsed load having a known upcoming magnitude, said voltage converter including a switching circuit receiving a switching signal with a duty cycle that is adjusted by a voltage controller, said method comprising forward-correcting the duty cycle of the switching signal in accordance with the known upcoming magnitude of the pulsed load.
