  • System and method for switched power supply with delay measurement
    Patent number: 10263518
    Abstract: According to an embodiment, a method of operating a switching power supply includes applying a periodic switching signal to a first switch that is coupled to an output node, detecting an offset delay between applying the periodic switching signal and a change in voltage of the output node, calculating a corrected midpoint of a half phase of the periodic switching signal based on the offset delay, generating a sampling pulse based on the corrected midpoint, and sampling a current at the output node according to the sampling pulse.
    Type: Grant
    Filed: February 1, 2017
    Date of Patent: April 16, 2019
    Assignee: INFINEON TECHNOLOGIES AG
    Inventors: Emanuele Bodano, Luca Bizjak, Maria Lagioia, Joachim Pichler
