Abstract: A lack of available responsive options for existing web sites and/or pages, and the wide spectrum under which they fall presents a challenge for a satisfying mobile user experience (UX) with a hosted collaboration service. Templates used to create a site and/or page may each have capabilities and features which “cross-over” into other templates. Deconstructing and rendering a web page into a native application experience at a mobile client may highlight a template's functionality to enhance the UX. For example, a server side application programming interface (API) may be provided for the mobile UX, a type of a page to be rendered may be determined, the page may be deconstructed into pieces, and the deconstructed pieces may be provided to rebuild the page at the mobile client natively. The page may be rendered on the mobile client with added elements based on the deconstructed pieces to enhance the mobile UX.

Abstract: Power consumption in a start-up circuit for a LED-based light bulb may be reduced by digitally switching a transistor of the start-up circuit coupled to the input voltage. When the transistor is digitally switched between on and off, a reduced amount of power is dissipated by the transistor, because it may not enter a saturation region of operation where the resistance of the transistor between drain and source terminals increases. The transistor may be coupled to a voltage regulator for generating one or more output voltages, including a supply voltage for a host controller IC. The transistor may be switched on and off by a digital signal generated by logic circuitry, which may decide to switch the transistor on and off based on a voltage level at an output of the voltage regulator.

Abstract: A system and method reduces power consumption by an electronic power control system when a controller of the electronic power control system reduces sense signal monitoring during a standby mode of the controller. The electronic power control system includes a controller to control a switching power converter. The controller operates in at least two modes, standby and active modes. Energy savings during standby mode can be achieved in a variety of current and/or voltage sensing configurations. During the standby mode, the controller generates a signal to at least intermittently disable sensing of an input voltage to the switching power converter or at least intermittently disabling sensing of an input voltage and an output voltage. Disabling sensing reduces energy losses associated with an input voltage sense signal itself and with circuitry in the controller used to process the input voltage signal.

Abstract: A power supply system and method includes a switch state controller that is operational to control a switching power converter during certain power loss conditions that cause conventional switch state controllers to have diminished or no functionality. In at least one embodiment, during certain power loss conditions, such as when an auxiliary power supply is in standby mode or when the switching power converter is not operating, a power supply for the switch state controller does not provide sufficient operating power to the switch state controller during certain power loss conditions. In at least one embodiment, during such power loss conditions power is generated for the switch state controller using sense input and/or sense output currents of the switching power converter to allow an integrated circuit (IC) switch state controller to generate a control signal to control a switch of the switching power converter.

Abstract: A power control system and method senses input and/or output voltages of a power supply using sense currents in order for an integrated circuit (IC) switch state controller to generate a control signal to control a switch of the power control system. By sensing sense currents, the power control system can eliminate at least one sense resistor used in a voltage sense system. The sense current(s) can be used to provide power and sensing to the switch state controller. In at least one embodiment, the sense current(s) provide power to the switch state controller when auxiliary IC power is unavailable or diminished, such as during start-up of the IC. In at least one embodiment, the IC draws more sense current from an input of the power control system than the output of the power control system to, for example, minimize impact on the output voltage of the power supply.

Abstract: A boosted auxiliary winding power supply for a switched-power converter circuit provides operating voltage for control and other circuits early in the start-up phase of converter operation. A boost circuit has an input coupled to the auxiliary winding to boost the voltage available from the auxiliary winding at least during start-up of the switched-power converter. The boost thereby provides a voltage that is greater than the voltage across the auxiliary winding during start-up of the switched-power converter. The boost circuit may be actively switched at a rate higher than a switching rate of the switched-power converter, to increase a rate of rise of the operating voltage. Polarity information, which may be provided from the switched-power converter control circuit, can be used to actively rectify the output of the auxiliary winding.
