External Power Supply Efficiency Ratings

Efficiency Standards and Ratings for External Power Supplies A power supply’s efficiency is simply the ratio between the energy it consumes and the energy it supplies. No device can be perfectly efficient; there will always be losses in heat or electromagnetic fields. The leading causes come from active component losses (MOSFET and diode switching losses) and, to a lesser extent, from passive component losses (resistors, capacitors, and inductor impedance losses). It moves towards utilizing higher Read Article
