Abstract: A system stores information of various electrical components and includes a computing resource. The resource receives design requirements indicative of a desired power supply design (e.g., an input voltage, an output voltage, an output current, and a value indicative of maximum output voltage ripple). The resource determines electrical components that comply with the input voltage, output voltage, and output current and then generate power supply designs that satisfy the input voltage, output voltage, and output current. For each power supply design, the resource calculates an output capacitor and an inductor. The capacitor is selected by adjusting the capacitor's ESR. A post ripple filter circuit may be added. Inductor ripple may be reduced by sizing the inductor for a target ripple. The provides the power supply designs in a ranked order.
