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