  • Method and system for maintaining output voltage regulation of a non-synchronous switching regulator providing voltage supply to a main load
    Patent number: 10367416
    Abstract: Method and system for maintaining output voltage regulation of a non-synchronous switching regulator providing a voltage supply to a main load. The method includes determining, using an electronic processor, that the main load is transitioning from a first load state to a second load state. The method also includes connecting, using the electronic processor, a switchable load to the non-synchronous switching regulator in response to determining that the main load is transitioning from the first load state to the second load state.
    Type: Grant

  • Method and apparatus for dissipating heat from an integrated circuit
    Patent number: 7521791
    Abstract: An apparatus (100) is provided for dispersing heat from an integrated circuit (202) to a heat sink (404). The apparatus (100) is formed on a nonconductive body (102) having at least two conductive surfaces (110, 112) disposed thereon. One of the conductive surfaces (110) is reflowed to a heat generating lead of the integrated circuit (202), and the other conductive surface (112) provides a surface for contacting a heat sink (404). The apparatus (100) and integrated circuit provide a package (200) which can be tape and reeled (300) for easy mounting to a printed circuit board (402) of a communication device (400).

  • Transistor mounting device
    Patent number: 5392193
    Abstract: A transistor mounting device (102) includes a recess area (112) for allowing a transistor (114)to be secured to the transistor mounting device (102) by turning the transistor a certain amount. Once the transistor (114) is secured into position to the transistor mounting device (102), a set of transistor pads (402) provide support and alignment to the transistor fins (116).
