  • Short Circuit and Soft Short Protection for Data Interface Charging
    Publication number: 20170346313
    Abstract: A switching power converter is provided that communicates with a mobile device to receive a value of a load detection current. The switching power converter adjusts the cycling of a power switch until a constant current mode of operation is entered with a known output current driving the mobile device. The switching power converter subtracts the load current from the output current to measure a soft-short circuit current.

  • Smart Grouping Control Method for Power Converter Switching Noise Management
    Publication number: 20170214329
    Abstract: A switching power converter is provided that cycles a power switch during a group pulse mode of operation to produce a train of pulses within a group period responsive to a control voltage being within a group mode control voltage range.

  • FREQUENCY HOPPING FOR REDUCING SWITCHING POWER CONVERTER NOISE
    Publication number: 20170214320
    Abstract: A switching power converter is configured to control switching noise by implementing a plurality of pulse width modulation modes of operation. The peak current in each pulse width modulation mode of operation is controlled so that an output power for the switching power converter is continuous with regard to transitions between the pulse width modulation modes.

  • Programming of a two terminal device
    Patent number: 9473033
    Abstract: A two-terminal device that is configured to respond to a voltage modulation of an input signal received through the two terminals by triggering an action. The two-terminal device is further configured to verify a result of the triggered action by modulating a current driven through the two termi+6nals.
