Abstract
Official abstract text for this publication.
An off-line power converter includes an integrated circuit power factor controller including a multi-function input terminal, a drive terminal for providing a drive signal to a gate of a drive transistor, a processing circuit coupled to the multi-function input terminal and, based on a signal received from the multi-function input terminal, providing at least one current signal representative of a current conducted in the off-line power converter, and at least one voltage signal representative of a voltage provided to a load, and a controller for providing the drive signal selectively in response to the at least one current signal and the at least one voltage signal.
First claim
Opening claim text (preview).
What is claimed is: 1. An off-line power converter, comprising: integrated circuit power factor controller including: a multi-function input terminal, wherein said multi-function input terminal is adapted to receive a voltage representative of a voltage proportional to a current flowing through a drive transistor and upon a voltage produced by a voltage sensing circuit; a drive terminal for providing a drive signal to a gate of a drive transistor; a processing circuit coupled…
