10.4.12.2 Over-Voltage Protection (OVP)
The power supply over-voltage protection is locally sensed. The power supply shuts down and
latches off after an over-voltage condition occurs. You can clear this latch by toggling the
#
PSON signal or using an AC power interruption. The following table contains the over-voltage
limits. The values are measured at the output of the power supply's connectors. The voltage
never exceeds the maximum levels when measured at the power pins of the power supply
connector during any single point of fail. The voltage never trips any lower than the minimum
levels when measured at the power pins of the power supply connector.
Exception: +5 VSB rail should be able to recover after an over-voltage condition occurs.
