DC DC Converters

DC-DC converters are electronic switching devices that convert a direct current (DC) input voltage to a different DC output voltage. They can also provide galva-nically isolated power conversion for applications where it is impossible or unfeasible to directly connect input and output sides of the converter. A wide range of power levels are available, from a few milliwatts to many kilowatts.

The ISU0205S15 is a high-performance, wide-bandwidth, single-channel DC-DC converter. It has a wide input voltage range of 10V-36V, and an output current of 15A, making it suitable for applications in computers, industrial automation, and other areas where low power DC-DC conversion is required. The ISU0205S15 uses a non-isolated switching architecture that enables a wide range of applications with low external component count.

Working Principle
