Abstract

See full text

This application discusses, among other things, zero current detection. In an example, a circuit for zero current detection can include a compensating circuit and a detecting circuit. The compensating circuit can be configured to feed back a compensating voltage to the detecting circuit according to an output voltage of a DC-DC converting circuit. The detecting circuit can be configured to dynamically adjust an intentional offset voltage according to the compensating voltage, and to perform zero current detection of the DC-DC converting circuit according to the adjusted Voffset.
