  • Patent number: 10811956
    Abstract: A controller for a multiple output power converter, including an error amplifier configured to generate an error signal based on a difference between an output signal of a multiple output power converter and a reference signal. A switch request circuit is configured to generate a request signal in response to the error signal. The switch request circuit is further configured to control a switching of a power switch of the multiple output power converter to transfer energy from an input of the multiple output power converter to an output of the multiple output power converter. A power limit fault circuit is configured to receive the request signal and the error signal, the power limit fault circuit further configured to generate a first fault signal in response to detection of an output overload or short circuit.

  • Publication number: 20200313561
    Abstract: Methods and apparatus for continuous conduction mode operation in multi-output power converters are described herein. During a switching cycle, secondary current may be delivered via a diode to a secondary output. Prior to beginning a subsequent switching cycle, a diverting current may be provided to a lower voltage secondary output on a parallel path. In this way diode current may be reduced to substantially zero prior to the subsequent switching cycle.

  • Patent number: 10523814
    Abstract: A robocall management system (RMS) comprises a service switching point switch, a service control point, and a robocall confirmation system, that all cooperate in processing incoming calls to a subscriber. If the call is not a robocall, the call will be delivered to the subscriber as normal. If the call is, or may be, a robocall, then call will be diverted to the robocall confirmation system, which will determine whether the caller is a live person or a computer playing an announcement. If the caller is a live person, then the call is offered to the subscriber. If the caller is a robocaller, then the robocall announcement is recorded by the robocall confirmation system and made available to the subscriber should they choose to listen to it. Various algorithms may be employed along with external data to ascertain a likelihood of whether the call is a robocall.

  • Publication number: 20190372470
    Abstract: Apparatus and methods for sequencing outputs in a multi-output power converter system are disclosed herein. During start-up multiple CC/CV outputs may be sequenced so that energy is first provided to a highest voltage secondary output and subsequently provided to a lowest voltage secondary output. Additionally, control may be exerted so as to concurrently and monotonically increase voltages during at least part of the start-up transient; and concurrent control may be further implemented using control circuitry and a variable reference generator. In some embodiments a variable reference may be generated from a capacitor voltage.

  • Publication number: 20190348900
    Abstract: A switched mode power converter has an energy transfer element that delivers an output signal to a load. A power switching device coupled to the primary side of the energy transfer element regulates a transfer of energy to the load. A secondary controller is coupled to receive a feedback signal and output a pulsed signal in response thereto. A primary controller is coupled to receive the pulsed signal and output a drive signal in response thereto, the drive signal being coupled to control switching of the power switching device. A compensation circuit generates an adaptively compensated signal synchronous with the pulsed signal. The adaptively compensated signal has a parameter that is adaptively adjusted in response to a comparison of the feedback signal with a threshold reference signal. The parameter converges towards a final value that produces a desired level of the output signal.

  • Patent number: 10355583
    Abstract: A controller for use in a power converter includes a comparator that receives an output signal representative of an output voltage of the power converter. The comparator generates a constant voltage signal in response to a comparison of the output signal and a reference signal. A switch request circuit receives the constant voltage signal and a fault signal. The switch request circuit generates a request signal in response to the constant voltage signal and the fault signal to control switching of a power switch of the power converter to control a transfer of energy from an input of the power converter to the output of the power converter. A power limit fault circuit receives the request signal. The power limit fault circuit generates the fault signal to indicate a fault existence in the power converter in response to a rate of consecutive request pulses greater than a threshold.
