PoE - DC/DC Converter

DC/DC Converters for Power Over Ethernet

DC/DC regulators are circuits that convert DC voltage from one level to another and maintain that voltage at a constant level. Electronic systems often have several sub-circuits, each with its own voltage level requirement that may be higher or lower than the main power supply. Step-up (boost) converters raise a voltage to a higher level, while step-down (buck) converters lower it. Learn More
