20110061113 | ACCESSORY AUTHENTICATION FOR ELECTRONIC DEVICES - Improved techniques to control utilization of accessory devices with electronic devices are disclosed. The improved techniques can use cryptographic approaches to authenticate electronic devices, namely, electronic devices that interconnect and communicate with one another. One aspect pertains to techniques for authenticating an electronic device, such as an accessory device. Another aspect pertains to provisioning software features (e.g., functions) by or for an electronic device (e.g., a host device). Different electronic devices can, for example, be provisioned differently depending on different degrees or levels of authentication, or depending on manufacturer or product basis. Still another aspect pertains to using an accessory (or adapter) to convert a peripheral device (e.g., USB device) into a host device (e.g., USB host). The improved techniques are particularly well suited for electronic devices, such as media devices, that can receive accessory devices. One example of a media device is a media player, such as a hand-held media player (e.g., music player), that can present (e.g., play) media items (or media assets). | 03-10-2011 |

20150061617 | ADJUSTING A CURRENT THRESHOLD OF A POWER SUPPLY IN RESPONSE TO A PORTION OF A CURRENT-PULSE PERIOD - An embodiment of a power-supply controller includes switching circuitry and an adjuster circuit. The switching circuitry is configured to cause a charging current to flow until the charging current has a predetermined relationship to a threshold, and to cause a discharging current to flow after the charging current. The adjuster circuit is configured to adjust the threshold in response to at least one of a charging period during which the charging current flows and a discharging period during which the discharging current flows. For example, a power supply may include such a power-supply controller to maintain a length of a current pulse, or of a portion thereof, within a particular range, such as approximately at a particular value, during a pulse-frequency-modulation (PFM) mode despite variations in one or more parameters such as input voltage, output voltage, filter capacitance, phase inductance, charging-current-sense impedance, and load, from their respective nominal values. | 03-05-2015 |
20150061618 | TRANSITIONING A POWER SUPPLY FROM A MODE TO ANOTHER MODE IN RESPONSE TO A LENGTH OF A PORTION OF A CURRENT PULSE - An embodiment of a power-supply controller includes a switching circuit and a transition circuit. The switching circuit is configured to generate a regulated output voltage by generating first current pulses at an approximately fixed frequency during a first mode, and generating second current pulses at a variable frequency during a second mode. And the transition circuit is configured to transition the switching circuitry from the first mode to the second mode in response to a length of one of the first current pulses. For example, a power supply may include such a power-supply controller to transition the supply from a PWM mode to a PFM mode under light-load conditions. To cause this transition at a predictable load point, the controller may monitor the lengths of the current pulses during the PWM mode, and may transition the supply to a PFM mode in response to the lengths being below a threshold. | 03-05-2015 |
20150061626 | SMOOTH TRANSITION OF A POWER SUPPLY FROM A FIRST MODE, SUCH AS A PULSE-FREQUENCY-MODULATION (PFM) MODE, TO A SECOND MODE, SUCH AS A PULSE-WIDTH-MODULATION (PWM) MODE - In an embodiment, an apparatus, such as a power-supply controller, includes a generator and an adjuster. The generator is configured to provide a switching signal that causes a power supply to generate a regulated output signal, and the adjuster is configured to impart a condition to the power supply while the power supply is operating in a first mode, the condition being approximately equal to a condition that the power supply would have if the power supply were operating in a second mode. For example, such an apparatus may be able to reduce or eliminate a transient on a regulated output signal (e.g., a regulated output voltage) when a power supply transitions from a first operating mode, such as a pulse-frequency-modulation (PFM) mode, to a second operating mode, such as a pulse-width-modulation (PWM) mode. | 03-05-2015 |
20150062108 | ADJUSTING A CURRENT THRESHOLD OF A POWER SUPPLY SUCH THAT AN OUTPUT RIPPLE VOLTAGE IS WITHIN A SET RANGE - In an embodiment, a power-supply controller includes switching circuitry and an adjuster circuit. The switching circuitry is configured to cause a charging current to flow until the charging current has a predetermined relationship to a threshold, and to cause a discharging current to flow to an output node that carries an output voltage after the charging current. And the adjuster circuit is configured to adjust the threshold such that a ripple voltage superimposed on the output voltage has an approximately constant magnitude. For example, a power supply may include such a power-supply controller to maintain the magnitude of the output ripple voltage within a particular range during a pulse-frequency-modulation (PFM) mode despite variations in one or more parameters such as input voltage, output voltage, filter capacitance, phase inductance, and charging-current-sense impedance, from their respective nominal values. | 03-05-2015 |
