General
The energy stored in a capacitor is described by $ E=\frac{LI^2}{2} $
A MOSFET can be used instead of the rectifier diode, a so called synchronous rectifier, to improve efficiency.
Skip Mode is a feature that improves efficiency at light loads. But it generates more noise that is difficult to filter.

Considerations
| Property | Pro | Con |
| High switch frequency | Smaller footprint | Lower efficiency |
| Higher inductance | Lower ripple | Bigger footprint |
| Lower inductor resistance | Higher efficiency | Bigger footprint |
