2.3.1 Dynamic Loading
The output voltages shall remain within limits specified in Table 9 for the step loading and
capacitive loading specified in Table 10, below. The load transient repetition rate shall be
tested between 50 Hz and 5 KHz at duty cycles ranging from 10%-90%. The load transient
repetition rate is only a test specification. The ∆ step load may occur anywhere within the MIN
load to the MAX load shown in Table 10.

2.4 Capacitive Loading
The power supply shall be stable and meet all requirements with the following capacitive
loading ranges. Min capacitive loading applies to static load only.

2.5 Protection Circuits
Protection circuits inside the power supply shall cause 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 15 sec and a PSON
#
cycle HIGH for 1sec shall be able to reset the power supply.
2.5.1 Over-Current Protection (OCP)
The power supply shall have current limit to prevent the +12 V and 5Vsb outputs from
exceeding the values shown 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
