A constant on-time (COT) controller for dc converters has received much attention recently because of its unique feature of high light-load conversion efficiency. In this paper, a control model is developed for the boost converters with the current-mode COT controller. Models are developed for predicting the loop stability and the step-load transient(More)
In recent years, LEDs have been increasingly used for back-light illumination for high-performance digital television applications. This is usually a wide-screen TV application in which array-connected LED strings and boost converter configuration are used, and dimming capability is a necessity. In such a control scheme, the LED current is precisely(More)
