Abstract
A controller and methodology for a power supply are disclosed. The controller includes output channels for providing a pulse width modulation (PWM) voltage signal for driving a load, for example, a microprocessor. Each channel provides a portion of the PWM signal. The controller receives user input information and uses that information to automatically determine window sizes. A window size defines the maximum output current level for a given window. The controller uses feedback signals to determine the current being drawn by the load, and selects the number of windows and channels that are needed to adequately provide that current. The controller selectively activates and deactivates the output channels accordingly. In response a change in the user input information the controller automatically adjusts the window sizes.
