Abstract
This document discusses, among other things, voltage converters and computed on-time voltage converters. In an example, an on-time generator for a voltage converter can include a timing capacitor configured to provide a timing voltage, a comparator configured to receive the timing voltage and a threshold voltage and to provide the timing signal using a comparison of the timing voltage and the threshold voltage, a current source configured to discharge the timing voltage of the timing capacitor after a start-up delay, and first and second compensation capacitors configured to bias the timing voltage of the timing capacitor to compensate for the start-up delay.
