Abstract

A regulated adaptive constant on-time (ACOT) boost converter is disclosed. Herein, the regulated ACOT boost converter includes a synchronous boost converter that can boost an input voltage to a higher output voltage in accordance with a duty cycle. The regulated ACOT boost converter also includes a well-known ACOT controller that determines the duty cycle with repeating cycles each consisting of a fixed on-time duration and a flexible off-time duration. Understandably, for the synchronous boost converter to operate efficiently, the input voltage needs to be lower than the output voltage. In this regard, in an embodiment, the regulated ACOT boost converter can further include a regulating circuit that can cause a dynamic adjustment to the duty cycle when the input voltage is approaching the output voltage. As a result, it is possible to keep the output voltage in regulation and prevent damage in the synchronous boost converter.
