Abstract

A DC-DC power converter includes a switched inductor power converter and a parallel linear voltage regulator. Two transistors are positioned in the switched inductor power converter to periodically set a bridge voltage thereby producing a square wave with a fixed frequency and variable duty cycle. An inductor and an output capacitor filter the bridge voltage so that only the average value of the bridge voltage is passed to the load. Parasitic impedance due to physical separation of the switched inductor power converter and the load is overcome by providing the parallel linear regulator with its own dedicated channel to the load.
