ORing and DPA Architecture
(Server/Telecom)
|
|
The Active ORing combines two or more power sources to create a redundant power source, preserving
the input power supply in case one of the input sources fails. In the event of an input power failure,
the active ORing circuit disconnects the non-functioning power source as quickly as possible to prevent
the system bus voltage from falling, and prevents large peak reverse currents.

The Active Solution
|
- VIN-OUT drop : 85mV (85% reduction in power losses vs. diode)
- Size: 50% smaller than the traditional solution with diodes
- Protection Features: Diagnostic Capability and Increased System Up-Time
