Video Descriptions

Modern DC to DC power converters are continuously striving for higher efficiency and power density. One topology used in demanding applications, such as -48V telecom and 42V automotive systems, is the Push-Pull topology, which is part of the Buck regulator family. There are several variations of the Push-Pull topology, which offers key advantages towards achieving next generation efficiency and density goals. An enhanced version of the Push-Pull topology is the Current-Fed Push-Pull or 'Cascaded' Push-Pull. Examples of Push-Pull and Cascaded power converters will be discussed, featuring the new LM5030 and LM5041 controllers.
