Switching Regulator Power Loss

Robert Dobkin - Chief Technical Officer Jan 9th 2012
Efficiency is a misleading number for comparison of switching regulators. The efficiency number can be manipulated by the input and output voltage, while power loss is more tightly tied to the actual circuit. This video explains why. ...
