  • Patent number: 8872577
    Abstract: A semiconductor device has pluralities of grid array terminals forming a grid array structure, e.g. a BGA structure, in which the output end of a built-in switch circuit is connected to multiple terminals of the grid array structure, thereby reducing the current that flows through each of the multiple terminals below a permissible level and minimizing the heat due to contact resistances of the multiple terminals in contact with the IC socket of the semiconductor device. Each pair of nearest neighbors of the multiple terminals is interposed by at least one further array terminal. The multiple terminals are all located at the outermost peripheral terminal positions of the grid array structure. Thus, the heat generated in the respective multiple terminals connected to the switch circuit is reduced, thereby minimizing the possibility of hazardous melting of the terminals.

  • Publication number: 20140312863
    Abstract: A switching transistor is configured such that its on resistance RON is switchable between at least two values RON1 and RON2. When the switching transistor is switched from off to on, a control circuit sets the on resistance of the switching transistor to the first value RON1 for a first period immediately after the switching of the switching transistor. Subsequently, for a second period until the switching transistor is turned off, the control circuit sets the on resistance of the switching transistor to the second value RON2 that is smaller than the first value RON1.
