Publication number: 20180109190Abstract: The disclosure relates to a DC-DC converter in which a first coil terminal is connected with an input terminal and a second coil terminal is connected, on the one hand, via a rectification switch to an output terminal and, on the other hand, via a control switch to a ground potential and a control circuit is configured to switch in successive switching cycles in each case in a regulating phase the rectification switch to be electrically blocking and the control switch to be electrically conducting, and in a rectifying phase to switch the control switch to be electrically blocking. A measuring component generates a measurement signal which signals a current intensity of a coil current, and a comparator circuit compares the measurement signal with a threshold value and the control circuit keeps the rectification switch electrically blocking in the rectifying phase and conducts the coil current via a bypass diode if the current intensity was continuously lower than the threshold value in the regulating phase.Type: ApplicationFiled: October 17, 2017Publication date: April 19, 2018Inventors: Christian STOEGER, Emil KOVATCHEV
