IntroductionDC-DC converters are devices that use the same basic principles as electrical transformers to convert between two different DC voltage levels. The term “DC-DC,” an acronym for Direct Current-Direct Current, refers to a type of power conversion technology that converts a higher direct current (DC) voltage to a lower DC voltage. In the DC to DC conversion process, it stores energy temporarily in an inductor, then disburses this energy at the required load voltage.The PT6655Q is a DC-DC converter that provides a variety of features. It features a high-efficiency, low-cost, high-reliability package that is well suited for a variety of applications including consumer electronics, automotive electronics, communication, and industrial devices.
