2.3.5 Protection Circuits
Protection circuits inside the power supply shall cause only the power supply’s main outputs to
shut down. If the power supply latches-off due to a protection circuit tripping, an AC cycle OFF
for 15sec and a PSON
#
cycle HIGH for 1sec shall be able to reset the power supply.
2.3.5.1 Current Limit (OCP)
The power supply shall have current limit to prevent the outputs from exceeding the values
shown in table below. If the current limits are exceeded the power supply shall shutdown and
latch off. The latch will be cleared by toggling the PSON
#
signal or by an AC power interruption.
The power supply shall not be damaged from repeated power cycling in this condition. 12VSB
will be auto-recovered after removing OCP limit.
