Abstract
Devices and methods are provided for controlling dead-time of a direct current to direct current (DC-DC) converter. A control circuit includes a first transistor having a source/drain terminal coupled to an output voltage of the DC-DC converter configured to provide current based on the output voltage. The control circuit also includes a digital up/down counter having an output terminal electrically coupled to an input terminal of a delay cell of the DC-DC converter. A current sensing circuit of the control circuit is electrically coupled to an input terminal of the digital up/down counter configured to receive the current and drive the digital up/down counter based on the current.
