DC DC Converters

DC to DC converters, or DC-DC converters, are designed to convert one DC voltage level to another DC voltage level. For instance, a converter could convert a 12V supply to a 5V one. DC-DC converters are used in a variety of applications, ranging from automotive applications to battery-charging applications.

ASQ24S04120-NS00 application field and working principle
