Abstract: A controller for a DC-DC converter that includes an inductor. The DC-DC converter has three phases of operation: a first phase, in which an input voltage charges the inductor; a second phase, in which the inductor discharges to a load; and a third phase, in which the inductor is disconnected from the load and in which the input voltage does not charge the inductor. The controller is configured to set a control-factor based on the input voltage of the DC-DC converter, and set the duration of the third phase based on the control-factor and the sum of the duration of the first phase and the second phase.

Abstract: A method for performing foreign object detection in an inductive wireless power transfer system is disclosed. In the embodiment, the method involves obtaining measurements from a base station of a wireless power transfer system during charging and determining transmitter energy loss in a power transmitter, Ptxloss, using the obtained measurements, wherein the transmitter energy loss, Ptxloss, is a function of at least Vcap and PTx, wherein Vcap is proportional to the voltage amplitude across the capacitor of an LC tank circuit in a power transmitter and PTx is the total power supplied to the power transmitter. The method also involves detecting the presence of a foreign object in response to the estimated transmitter energy loss.

Abstract: An integrated circuit (IC) includes an input/output (I/O) circuitry with a first circuitry section including I/O pins and a second circuitry section including I/O pins. The first and second circuitry sections are mutually exclusive sections of the I/O ring. The first circuitry section includes a first I/O pin configured to receive an input voltage from a first energy source and a second I/O pin connectable to an external startup capacitor. A startup circuit is coupled to the first I/O pin and the second I/O pin. Upon receiving the input voltage from the first energy source, the startup circuit enters a during the startup phase and isolates the first circuitry section from the second circuitry section, and provides charge to the external startup capacitor. In response to achieving a predetermined minimum charge on the external startup capacitor, the first circuitry section is connected to the second circuitry section, and the startup phase ends and the IC transitions to a functional mode of operation.
