Abstract
The present invention is a switching power converter that includes multiple energy transfer legs feeding a common energy storage circuit. Each energy transfer leg has a unique switching signal with a common switching frequency. The unique switching signals are phase-shifted from each other to minimize generation of switching noise within the passband of a received RF signal. Each unique switching signal has an active state during which energy may be transferred to the energy transfer leg, and an inactive state during which energy may be transferred from the energy transfer leg to the common energy storage circuit.
