DC-DC Converters

A DC-DC converter, also known as a synchronous or switching regulator, is an electrical device that converts one form of direct current (DC) electricity to another. This type of converter is often used in telecommunications, consumer electronics, motor control, and the operation of computers. Its primary purpose is to regulate the voltage of a given power supply in order to stabilise it or make it more suitable for its intended purpose. The output voltage of a DC-DC converter can be either higher or lower than the input voltage.

One of the most important types of DC-DC converters is the VWRBS2-D48-S5-SIP. This is a high-performance switching regulator in a surface mount industry package, offering up to 48V output voltage and 5A current. It is ideal for applications in the fields of distributed power, LED lighting, and telecoms.
