Abstract
Official abstract text for this publication.
A controller integrated circuit (IC) for controlling a power converter uses one or more IC pins having plurality of functions such as configuration of a parameter supported by the controller IC and shutdown protection. Several different functions may be supported by a single IC pin, thereby reducing the number of pins required in the controller IC and also reducing the cost of manufacturing the controller IC. The controller IC may also share a comparison circuit among different pins and the different functions provided by those pins. Use of a shared comparison circuit further reduces the cost of manufacturing the controller IC without sacrificing the performance of the IC.
First claim
Opening claim text (preview).
What is claimed is: 1. A controller integrated circuit (IC) for controlling a power converter, the controller IC comprising: a first IC pin to connect to circuitry of the power converter that is external to the controller IC; control circuitry operating in a first mode or a second mode, the first mode and second mode corresponding to distinct periods of time, wherein in the first mode the control circuitry configures an operating parameter of the controller IC based on a first…
