Abstract
Official abstract text for this publication.
Simple and efficient techniques for closed loop control of a boost converter. In an aspect, a current feed-forward (CFF) mode of operation includes providing current information to a control logic block controlling transistor switches of the boost converter to advantageously smooth the signals present in the closed loop control of the system. In another aspect, a modified peak current (MPC) mode of operation includes providing a simplified control mechanism based on a peak current mode of operation. Both CFF mode and MPC mode may share similar circuit elements, allowing a single implementation to selectively implement either of these modes of control. Further techniques are provided for determining average current information for the logic block.
First claim
Opening claim text (preview).
The invention claimed is: 1. An apparatus comprising: a control logic block configured to control low-side and high-side switches coupled to an inductor, wherein: the high-side switch is controlled to selectively couple the inductor to an output voltage coupled to a load and a storage capacitor; the low-side switch is controlled to selectively couple the inductor to a ground voltage; and the control logic block is configured to control the switches based on inputs comprising…
