  • Patent number: 11031869
    Abstract: A dual mode switching regulator includes a PWM/PFM control architecture with PFM frequency foldback based on extending switching cycle off time TOFF. A controller includes a PWM/PFM clock generator that, in response to assertion of a TOFF control signal, extends the nominal PWM switching cycle off-time TOFFnom for an extended off-time TOFFext (variable), so that switching cycle off-time is [TOFFnom+TOFFext]. A TOFF modulator generates the TOFF control signal based on generating a TOFF control voltage from an ITOFF control current equal to [IPWM-IPFM], generated by sourcing an IPWM reference current, and, in response to a PFM load condition, sinking an IPFM control current. The TOFF control signal is asserted when the TOFF control voltage is not substantially equal to a TOFF reference voltage at the end of TOFFnom, to cause the PWM/PFM clock generator to extend switching cycle off-time to [TOFFnom+TOFFext], with the duration of TOFFext determining PFM switching frequency.

  • Patent number: 11027656
    Abstract: A hub that receives sensor data streams and then distributes the data streams to the various systems that use the sensor data. A demultiplexer (demux) receives the streams, filters out undesired streams and provides desired streams to the proper multiplexer (mux) or muxes of a series of muxes. Each mux combines received streams and provides an output stream to a respective formatter or output block. The formatter or output block is configured based on the destination of the mux output stream, such as an image signal processor, a processor, memory or external transmission. The output block reformats the received stream to a format appropriate for the recipient and then provides the reformatted stream to that recipient.
