  • Voltage converter with high efficiency
    Patent number: 8189354
    Abstract: A voltage converter transmits energy in multiple stages using a charge pump so as to decrease the voltage rating of the secondary side of the transformer and reduce the size of the transformer. Meanwhile, the voltage converter stores and recycles the leakage inductance energy by using a snubber circuit so as to increase the efficiency.
    Type: Grant
    Filed: February 22, 2010
    Date of Patent: May 29, 2012
    Assignee: Analog Integrations Corporation
    Inventors: Szu-Ming Chiang, Wei-Ming Chen, Chi-Hung Tsai
  • LIGHT EMITTING DIODE CURRENT CONTROL CIRCUIT CAPABLE OF ENERGY RECYCLING
    Publication number: 20120119663
    Abstract: Alight emitting diode current control circuit capable of energy recycling includes at least one diode and at least one converter. The diode has an anode terminal, and a cathode terminal for coupling to a first terminal of at least one series of light emitting diodes. The converter has a first terminal coupled to an anode terminal of a corresponding diode, a second terminal for coupling to a second terminal of a series of light emitting diodes corresponding to the converter, a third terminal, and a fourth terminal coupled to ground.
