Assignee:

Primarion, Inc. - Tempe AZ

International Classification:

H02H 300

US Classification:

361 64, 361 931, 365226

Abstract:

A method, apparatus, and system for providing operating power and transient suppression power to a microelectronic device are disclosed. The system includes a primary regulator to supply nominal operating power and to respond to relatively slow transient events and a transient suppression regulator to respond to fast transient power events. The system also includes a sense circuit to detect when a transient event occurs and to send a signal to the transient suppression regulator to supply or sink current to the load in response to a sensed transient power event.

Abstract:

A semiconductor device package is disclosed which includes inter-digitated input and output bond wires configured to increase the negative mutual inductive coupling between the wires, thus reducing the overall parasitic inductance of the device. In one embodiment, the microelectronic component includes a semiconductor device coupled to a substrate, such as a lead frame, a first set of bond wires connected to the semiconductor device for providing current flow into the semiconductor device, and a second set of bond wires that are in a current loop with the first set of bond wires and are connected to the semiconductor device for providing current flow out of the semiconductor device, wherein the first and second set of bond wires are configured in an inter-digitated pattern to increase the magnitude of mutual inductive coupling between the first and second set of bond wires. In one embodiment, the semiconductor device comprises a single semiconductor chip and the lead frame comprises a Quad Flat No-Lead (QFN) lead frame. Other embodiments include multiple chips and/or multiple lead frames.

Assignee:

Primarion, Inc. - Phoenix AZ

International Classification:

H02H 3/22

US Classification:

361 18, 361111

Abstract:

Disclosed is a digitally controlled multi-phase voltage regulator system providing regulated power to electronic components that have variable power requirements. Power is supplied by one or more power integrated circuits (IC) each having a high side power switch controlled by pulse width modulated signals and a low side power switch. The power IC senses voltage at the load and has an on-chip current mirror for generating a current that is a ratio of current delivered to the load. The power IC also has current limiting and on-chip temperature sensing components. The voltage and current information is digitized and provided to a control integrated circuit (IC). The control IC receives this digitized information as well as user provided parameters and, in the regulation mode of operation, provides digitized pulse width modulated control signals to the power IC. In an active transient response mode of operation, the control IC provides signals to turn either the high side switches or low side switches ON. Fault detection circuitry identifies over voltage, under voltage, and excessive temperatures.

Appl. No.:

5/582607

Inventors:

Robert L. Carroll - Greenville SC

International Classification:

A47F 100
B65D 2510

US Classification:

312 71

Abstract:

A piston is provided for a roving can of the spring type wherein the piston has a cylindrical marginal skirt and an inwardly extending conical downwardly inclined surface for receiving the central portion of the sliver core so as to relieve the tendency of the sliver to form a hard central core and increase the capacity of the can. The conical surface extends adjacent the bottom of the skirt and a substantially horizontal bottom extends thereacross in order to maximize the amount of sliver which may be distributed in the can.
