    Abstract: A method of ensuring power delivery in a universal serial bus (USB) interface between a device and a counterpart device, the device including a port controller and a USB receptacle. The method includes the port controller attempting to detect an abnormal state in which a leakage current occurs in the USB receptacle using at least one pin of the USB receptacle; and when the abnormal state is detected, the port controller turning OFF a switch connected between a power pin of the USB receptacle and an internal circuit of the device, and determining to enter an unattached state of being separated from the counterpart device.

    Abstract: A voltage converter includes a switching driver, a controller, a low-pass filter and a pulse width modulation signal generator. The switching driver includes a pull-up switching circuit connecting an input voltage to a switching node in response to a pull-up signal and a pull-down switching circuit connecting a ground voltage to the switching node in response to a pull-down signal. The controller generates the pull-up signal and the pull-down signal in response to a pulse width modulation signal and measures pull-up and pull-down turn-on times of the pull-up and pull-down switching circuits in real time to control a dead time. The low-pass filter filters a switching voltage signal on the switching node to generate an output voltage. The pulse width modulation signal generator generates the pulse width modulation signal based on a reference signal and the output voltage.
