Practical Comparisons of 3 different DC-DC Control Modes

Certain end-equipment, like communications, server, industrial, and personal electronics have design challenges solved by the DC/DC converter’s control-mode.  This session will compare and contrast 3 different devices using 3 different control modes under the same design criteria to see how each control mode solves particular size, efficiency, external component, ripple and transient response design challenges.
