Switching converter with current sensor

Abstract

Abstract A switching converter having a current sensor and a comparator. In order to make the influence of switching-on current surges ineffective on the response of the comparator, an electronic switch (811, 832) is provided at the reference-voltage input or at the output of the comparator, which electronic switch (811, 832) is switched off during a time period which includes the switching-on current surges and excludes the response time of the comparator, and which makes the initial current surges of the current flowing through the current sensor ineffective. The switching converter can, in particular, be a forward converter and/or flyback converter. <IMAGE>
