Switching DC-DCs regulate the output voltage based on energy flow into and from the DC-DC by controlling the duty cycle of the on and off states. When the switch is conducting, energy flows from the input source into the converter and in the case of a buck, some of this gets stored in the inductor as magnetic energy (0.5*LI2) while some gets delivered directly to the output (forward topology).

A fuse is an electrical or electronic circuit protection device that protects a circuit against overcurrent, either by melting or fusing open its conductive element when excessive current flows through it. Some fuses are single-use or “one-shot” designs; others are reusable designs. This is an important distinction in the marketplace among design engineers.

Advantages and disadvantages of MLCC downsizing are discussed in AVX technical papers written by Frank Hodgkinson and Maureen Strawhorne.
As integrated circuits (ICs) continue to pack more functionality into smaller packages, the need for bulk off-chip capacitance remains. In resonant circuits, such as phase-lock-loops (PLLs) and switching regulators, precision class one ceramic capacitor may be required.
