Referenced to load current and setpoint at
onset of transient. Recovery time to within 1%

Output to return
Channel Fault Operation
(Output to Return)
12V Payload Power Output under fault is
shutdown. 3V3 MP on the same channel
is not affected. The other channels are not
affected
After removal of fault, the output channel is
available again under control of the Carrier
Manager. PM_OK# is not de-asserted and
redundant failover is not initiated
Channel Fault Operation
(Output to Output)
No damage to Power Module Either or both outputs may
shut down until fault is removed
PS1# Extraction Delay 100 μs maximum Time from de-assertion of PS1# to disabling of
the channel outputs and de-assertion of the
ENABLE# signal

Note 1: All channels and outputs must be confi gued by the carrier manager with the exception of MCH and CU channels and outputs
which are confi gured during Startup and/or autonomous operation,
Note 2: All measurements are made at the output connector of the Power Module. Unless otherwise specifi ed,specs apply to all AMC,
MCH, and CU outputs.
Note 3: Measured with a 0.1 μF ceramic and 10 μF tantalum capacitor on any output and oscilloscope bandwidth set for 200 MHz.
Note 4: Consult with the factory if other outputs are expected to product signifi cant ripple current.
