Typical reasons to use a DC/DC converter include but are not limited to converting a DC voltage from a higher voltage to a lower voltage or a lower voltage to a higher one, converting a positive voltage to a negative voltage and vice versa, adding electrical isolation and adding regulation to an unregulated voltage. Whatever the reason, there are a large variety of DC/DC converters to choose from in today’s market. An engineer can pick and choose a unit based on a very specific set of requirements or criteria with little compromise.
