The ZCD includes a ZCD integrator configured to receive a switch voltage and an output voltage of a power stage of the DC-DC converter and to generate a zero-crossing detect signal based, at least in part, on the received switch voltage and output voltage, where the zero-crossing detect signal is configured to indicate an output current in an output inductor of the power stage of the DC-DC converter is approximately zero. The ZCD may also include a ZCD offset calibrator configured to receive the switch voltage and generate a ZCD calibration offset based, at least in part, on the received switch voltage, where the ZCD integrator is configured to generate the zero-crossing detect signal based, at least in part, on the ZCD calibration offset."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Zero-crossing detector for DC-DC converter systems and methods","description":"Embodiments described herein provide a zero-crossing detector (ZCD) for a direct current to direct current (DC-DC) converter.
