Method And Apparatus For Providing Power Signals To Operating Circuitry Mounted On Circuit Boards
US Patent:
6738268, May 18, 2004
Filed:
Nov 28, 2001
Appl. No.:
09/995919
Inventors:
David Sullivan - Londonderry NH
Robert MacArthur - Leominster MA
Robert MacArthur - Leominster MA
Assignee:
EMC Corporation - Hopkinton MA
International Classification:
H02M 7517
US Classification:
363 49, 363 65, 323901
Abstract:
A technique involves providing a set of soft start power signals to operating circuitry mounted on a circuit board. In particular, the technique involves enabling (i) a first converter to provide a first soft start power signal to the operating circuitry and (ii) a second converter to provide a second soft start power signal to the operation circuitry. Additionally, the technique involves providing a first control signal that indicates whether the first converter properly provides the first soft start power signal, and providing a second control signal that indicates whether the second converter properly provides the second soft start power signal. Furthermore, the technique involves disabling the first converter if the second control signal indicates that the second converter improperly provides the second soft start power signal, and disabling the second converter if the first control signal indicates that the first converter improperly provides the first soft start power signal.
