Buck converter current ratio
WebThis converter produces an output voltage V that is greater in magnitude than the input voltage V g. Its conversion ratio is M(D) = 1/(1 – D). In the buck-boost converter, the … WebA buck converter or step-down converter is a DC-to-DC converter which steps down voltage (while stepping up current) from its input (supply) to its output (load). It is a class of switched-mode power supply.
