Switch Mode Power Conversion
A Switch Mode DC/DC Converter output/input voltage ratio can be any value, including a negative
value. That property is not covered by any Linear Voltage Converter, so most power conversion use-
cases can be solved by Switch Mode, especially in the area of high power, where efficiency and form-
factor are vital.

Switch Mode DC/DC Conversion
Switch mode conversion is always an “active” conversion, in the sense there has to be active, working
semiconductors in the input-to-output transfer path. The presence of at least one winded component,
such as an inductor, is also essential.
