Patent Number Title Of Patent Date Issued
7615822 Diffused drain transistor November 10, 2009
A transistor has a source that includes a first impurity region with a first volume and a first surface area on a surface of the transistor. The transistor also has a drain that includes a second impurity region with a second volume and a second surface area on a surface of the transisto
6703888 Method of operating circuit with FET transistor pair March 9, 2004
A method for use with a switch having a field-effect transistor (FET). The method includes restricting the drain-source voltage of the FET to a predetermined range, and then switching the FET. In general, in one aspect, the invention features a circuit having source, drain and gate t
6642697 Switching regulator with multiple power transistor driving voltages November 4, 2003
A voltage regulator has an input terminal, an output terminal, a first transistor connecting the input terminal to an intermediate terminal, a second transistor connecting the intermediate terminal to ground, a controller that drives the first and second transistors to alternately co
6529056 Circuit with FET transistor pair March 4, 2003
A circuit, and a method and computer program product for use with a switch having a field-effect transistor (FET). The method and computer program product include restricting the drain-source voltage of the FET to a predetermined range; and then switching the FET. In general, in one
6433614 MOSFET-based switch August 13, 2002
A circuit, and a method and computer program product for use with a switch having a field-effect transistor (FET). The method and computer program product include restricting the drain-source voltage of the FET to a predetermined range; and then switching the FET. In general, in one
6400126 Switching regulator with multiple power transistor driving voltages June 4, 2002
A voltage regulator has an input terminal, an output terminal, a first transistor connecting the input terminal to an intermediate terminal, a second transistor connecting the intermediate terminal to ground, a controller that drives the first and second transistors to alternately co
6329801 Switching regulator control system and method December 11, 2001
A voltage regulator with an input terminal to be coupled to an input voltage source and an output terminal to be coupled to a load. The voltage regulator has a first switch to intermittently couple the output terminal to the input terminal, a voltage sensor to detect a voltage at the out
6271651 Inductor shorting switch for a switching voltage regulator August 7, 2001
A switching regulator has first, second, third and fourth terminals. The switching regulator includes a power switch, a rectifier switch, a filter, a shorting switch and a controller operable in a plurality of modes to open and close the switches. The power switch is disposed between the
