Classification: CPC H | IPC H

Claim 0:
1. A control circuit for controlling dead-time of a direct current to direct current (DC-DC) converter, the control circuit comprising:
a first transistor comprising a source/drain terminal coupled to an output voltage of the DC-DC converter configured to provide current based on the output voltage;
a digital up/down counter comprising an output terminal electrically coupled to an input terminal of a delay cell of the DC-DC converter configured to modify or maintain a delay time of the delay cell to minimize or eliminate the dead-time of the DC-DC converter;
a current sensing circuit 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; and
a capacitor electrically coupled between the current sensing circuit and the input terminal of the digital up/down counter.
