Choose the Right Regulator for the Right Job: Part 3, Component Selection

By: Don Corey

Abstract: This application note is part 3 of a three-part series on power regulators. In part 1 , we discussed regulator control schemes and examined the critical differences between current-mode (CM) and voltage-mode (VM) control. In part 2, we discussed pulse frequency modulation, hysteretic, and constant on-time control techniques. Now that we understand the basic fundamentals of these different converter types, in part 3, we will look at some regulator examples, proceeding from component selection to actual design.
