System For Suspending Operation Of A Switching Regulator Circuit In A Power Supply If The Temperature Of The Switching Regulator Is Too High
US Patent:
6721893, Apr 13, 2004
Filed:
Jun 12, 2000
Appl. No.:
09/591993
Inventors:
Chris Tressler - Austin TX
Mary Chen - Austin TX
Mary Chen - Austin TX
Assignee:
Advanced Micro Devices, Inc. - Sunnyvale CA
International Classification:
G06F 126
US Classification:
713300, 713324, 713340
Abstract:
A thermal protection circuit for high output power supplies. A power supply circuit includes a switching control circuit coupled to a switching regulator circuit. The switching control circuit is configured to generate a plurality of switching control signals for controlling the switching regulator circuit. The power supply circuit also includes a temperature sensitive circuit which includes a thermistor. The temperature sensitive circuit is configured to provide a variable voltage level output to the phase control circuit. The switching control circuit is also configured to suspend operation of the switching regulator circuit upon detecting a predetermined voltage level at the output.

Efficiency Of A Multiphase Switching Power Supply During Low Power Mode
US Patent:
6281666, Aug 28, 2001
Filed:
Mar 14, 2000
Appl. No.:
9/523107
Inventors:
Chris Tressler - Austin TX
Carl Hernandez - Austin TX
Mary Chen - Austin TX
Carl Hernandez - Austin TX
Mary Chen - Austin TX
Assignee:
Advanced Micro Devices, Inc. - Sunnyvale CA
International Classification:
G05F 140
US Classification:
323272
Abstract:
A multiphase power supply that minimizes losses during a low power mode+. In a particular embodiment, a multiphase power supply may include a plurality of switching regulators coupled in parallel with respect to one another. The multiphase power supply further comprises a phase control circuit coupled to each of the switching regulators. The phase control circuit is configured to generate a plurality of control signals for controlling the switching of the switching regulators so that they are out of phase with respect to one another. During the low power mode of operation of the microprocessor, the phase control circuit is configured to selectively suspend operation of a subset of switching regulators by removing or disabling at least one of the plurality of control signals to each of the subset of switching regulators.
