1. Circuitry comprising:
- a first switching converter of a first switching power supply and configured to receive a direct current (DC) power supply signal;
an energy storage element of the first switching power supply;
a first inductive element of the first switching power supply and coupled between the first switching converter and the energy storage element;
a first snubber circuit of the first switching power supply and coupled across the first inductive element; and
switching control circuitry of the first switching power supply and configured, to during a continuous conduction mode (CCM), allow energy to flow from the energy storage element to the first inductive element, and during a discontinuous conduction mode (DCM), not allow energy to flow from the energy storage element to the first inductive element,wherein the first switching power supply is configured to receive and convert the DC power supply signal to provide a first switching power supply output signal based on a setpoint.

Abstract
Circuitry, which includes a direct current (DC)-DC converter having a first switching power supply is disclosed. The first switching power supply includes a first switching converter, an energy storage element, a first inductive element, which is coupled between the first switching converter and the energy storage element, and a first snubber circuit, which is coupled across the first inductive element. The first switching power supply receives and converts a DC power supply signal to provide a first switching power supply output signal based on a setpoint.
