Feedback loop conception methodology for step-down continuous switching DC/DC converter

The stability and the dimensioning of a step-down switching voltage regulator feedback loop remain a complex task. An analytical approach allows dimensioning of all the components, strongly facilitating this task. In this article, a mathematical analysis is developed in order to determine the values of the passive component of the feedback loop, taking into account the tolerances of the various components. © 2008 IEEE.
