Question

HOW DOES A DC TO DC CONVERTER WORKS???

Answer 1

You mean an AC to DC Converter?

Answer 2

A DC to DC converter works by changing the voltage levels from say 5 v to 9 v. The result can often mean a change in current to maintain the same power, but not necessarily.

An operational amplifier is one way to accomplish this task.

Answer 3

Oh I get it. A *step-up voltage transformer*?

Answer 4

Transformers work with AC. You need active circuits to step up or down DC.
