  • Patent number: 10153702
    Abstract: Circuits and methods within a switched-mode power supply (SMPS) controller are provided. The SMPS controller includes an SMPS power stage which is integrated within the same package, and which has a first power switch. The first power switch is used to supply current to a power supply for the SMPS controller during a start-up phase of the SMPS, thereby charging this power supply prior to normal operational mode of the SMPS. A lead of the SMPS controller is connected to a control terminal of the first power switch during the start-up phase. After the start-up phase, this same lead is instead routed to an input source voltage monitor, and is used for detecting overvoltage or undervoltage conditions at the SMPS input power source.

  • Patent number: 9655181
    Abstract: Techniques are described for controlling an amount of current flowing through one or more light-emitting-diodes (LEDs), without sensing input and/or output voltage, so that the amount of current flowing through the one or more LEDs is approximately equal to a target current level. The techniques provide for coarse and fine tuning of the amount of time a transistor, through which the current flows, is turned on to control the amount of current flowing through the one or more LEDs.

  • Patent number: 9601992
    Abstract: This disclosure relates to a switching power supply with regulated voltage suppression to reduce transformer audio noise. The switching power supply is operable to be fed a zero crossing voltage and to generate an output voltage. The output voltage may have a voltage level set using a modulated gate signal. A circuit is provided to reduce audio noise in a switching power supply by setting a ringing suppression time of the modulated gate signal to a first time period when the zero crossing voltage is below a predetermined voltage threshold and to a second time when the zero crossing voltage is above the predetermined threshold voltage.

  • Patent number: 8943763
    Abstract: Damping arrangement for low, medium and high-rise structures (1) using bidirectional damping means (5) such as visco-elastic Gensui damping devices, placed between two parallel elements of the structure (1), such as a core (2) and a perimeter column (3), or between two cores. Oscillatory or other flexural or shear deformations of the structure (1) are damped by damping axial movements between the two elements (2, 3), and simultaneously damping orthogonal movements between the two elements (2, 3). Outriggers (6, 7, 8) are used to enhance the axial damping moment, and the bidirectional damping means (5) may be installed in pairs, working in opposition to each other to damp dynamic shear or flexural forces in the orthogonal plane.

  • Patent number: 8879280
    Abstract: This disclosure relates to a switching power supply with regulated voltage suppression to reduce transformer audio noise. A switched mode power supply (SMPS) may supply power at different levels according to output loads. A switching frequency of the SMPS may be adjusted according to the output load. The switching may be subject to a ringing suppression time, a maximum on time, and a maximum switching period. By controlling the switching frequency subject to these quantities, the audible noise of an SMPS may be reduced or eliminated.
