Switching Regulator Efficiency. The average power values are. The energy losses involved in moving chunks of energy around in this way are relatively small and the result is that a switching regulator can typically have 85 efficiency.

Evaluating a switching regulator. Switching regulators are able to generate output voltages that are higher than the input voltage or of opposite polarity unlike linear regulators. Since their efficiency is less dependent on input voltage they can power useful loads from higher voltage sources.
To further improve their efficiency it is helpful to understand the basic mechanism of power loss.
Switching regulators are efficient because the series element is either fully conducting or switched off so it dissipates almost no power. On the other side switching regulator use inductor diode and a power switch to transfer energy from its source to the output. Practical implications of poor efficiency. The energy losses involved in moving chunks of energy around in this way are relatively small and the result is that a switching regulator can typically have 85 efficiency.
