Abstract

Official abstract text for this publication.

In one implementation, a circuit for producing an average output inductor current indicator in a voltage converter is configured to start a counter when a high side power switch turns on, to sense a sample current through an output inductor of the voltage converter after the high side power switch turns off and when a low side power switch is on, and to register a first count of the counter when the low side power switch turns off. The circuit is further configured to register a second count of the counter when the high side power switch subsequently turns on, and to produce the average output inductor current indicator based on the sample current and the first and second counts of the counter.

First claim

Opening claim text (preview).

The invention claimed is: 1. A circuit for producing an average output inductor current indicator in a voltage converter, said circuit configured to: start a counter when a high side power switch turns on; sense a sample current through an output inductor of said voltage converter after said high side power switch turns off and when a low side power switch is on; register a first count of said counter when said low side power switch turns off; register a second count of said…
