| 20100288528 | COAXIAL CABLES HAVING LOW BOND PRECOAT LAYERS AND METHODS OF MAKING SAME - A coaxial cable includes an inner conductor, a dielectric layer surrounding the inner conductor, an outer conductor surrounding the dielectric layer, and a precoat layer disposed between the inner conductor and the dielectric layer. The precoat layer is adhesively bonded to the inner conductor and to the dielectric layer, and includes a blend of polymeric material and polymeric wax. The adhesive strength of the precoat layer is reduced by the polymeric wax such that the precoat layer can be removed completely and cleanly from the inner conductor as a result of shear forces applied to the precoat layer by standard commercially available coaxial cable stripping tools. | 11-18-2010 |

| 20080278123 | Switching regulator circuit, system, and method for providing input current measurement without a dedicated input current sense element - A synchronous regulator includes a controller coupled to receive a reference signal and a feedback signal from the regulator operable to provide a pulse width modulation (PWM) signal at its output. The regulator includes at least one gate driver coupled to receive the PWM signal, and a synchronous output switch having a phase node there between controlled by the gate driver, and regulator input current measurement circuitry. The regulator input current measurement circuitry comprises a circuit operable for providing a signal representative of at least one phase node timing parameter, a sensing circuit operable for sensing inductor or output current provided by the regulator, and a calculation circuit coupled to receive the signal representative of the phase node timing parameters and the inductor or output current and is operable to determine the input current. | 11-13-2008 |
| 20080303495 | POWER SUPPLY WITH A MAGNETICALLY UNCOUPLED PHASE AND AN ODD NUMBER OF MAGNETICALLY COUPLED PHASES, AND CONTROL FOR A POWER SUPPLY WITH MAGNETICALLY COUPLED AND MAGNETICALLY UNCOUPLED PHASES - An embodiment of a power supply includes an input node operable to receive an input voltage, an output node operable to provide a regulated output voltage, an odd number of magnetically coupled phase paths each coupled between the input and output nodes, and a first magnetically uncoupled phase path coupled between the input and output nodes. Such a power supply may improve its efficiency by activating different combinations of the coupled and uncoupled phase paths depending on the load conditions. For example, the power supply may activate only an uncoupled phase path during light-load conditions, may activate only coupled phase paths during moderate-load conditions, and may activate both coupled and uncoupled phase paths during heavy-load conditions and during a step-up load transient. | 12-11-2008 |
| 20080309299 | Inductor assembly having a core with magnetically isolated forms - An embodiment of an inductor assembly includes a core, a first conductor, and a second conductor. The core includes first and second members, a first group of one or more forms extending between the members, a second group of one or more forms extending between the members, and an isolating region that magnetically isolates the first group of forms from the second group of forms. The first conductor is wound about a first one of the forms in the first group, and the second conductor is wound about a second one of the forms in the second group. Such an inductor assembly may allow both coupled and uncoupled inductors to be disposed on a common core, thus potentially reducing the cost and size of the inductors as compared to the coupled inductors being disposed on one core and the uncoupled inductors being disposed on another core. | 12-18-2008 |
| 20080315982 | COUPLED-INDUCTOR CORE FOR UNBALANCED PHASE CURRENTS - An embodiment of a coupled-inductor core includes first and second members and first and second forms extending between the first and second members. The first form has a parameter (e.g., length) of a first value, and is operable to conduct a first magnetic flux having a first density that depends on the first value of the parameter. The second form is spaced apart from the first form, has the parameter (e.g., length) of a second value different from the first value, and is operable to conduct a second magnetic flux having a second density that depends on the second value of the parameter. Because two or more of the forms of such a core may have different values for the same parameter, the core may be suitable for use in a multiphase power supply where the currents through the phases are unbalanced. | 12-25-2008 |

| 20110109284 | SYSTEM AND METHOD FOR EQUALIZING THE SMALL SIGNAL RESPONSE OF VARIABLE PHASE VOLTAGE REGULATORS - A control circuit for a variable phase voltage regulator comprises an error amplifier to generate a difference signal based on a difference between a reference voltage and a signal representative of a voltage at an output node of the variable phase voltage regulator. The control circuit also comprises a variable phase compensator to amplify the difference signal to produce a modified difference signal to compensate for effects of varying the number of active phases in the variable phase voltage regulator, wherein the amplification is proportional to a ratio of total number of phases in the variable phase voltage regulator to number of active phases in the variable phase voltage regulator. | 05-12-2011 |
| 20120074924 | SYSTEM AND METHOD FOR OPEN LOOP MODULATION TO DETECT NARROW PWM PULSE - An open loop modulation network for a voltage regulator including a latch network, an output sense network, a timing network, and pulse control logic.

The timing network initiates a delay period in response to the output pulse indication and resets the latched control pulse indication after expiration of the delay period. The pulse control logic terminates the output pulse after the latched control pulse indication is reset and the pulse control signal is negated, whichever occurs last. Very narrow input pulses are detected and either a minimum output pulse is generated or the output pulse is based on the pulse control signal. | 03-29-2012 |
