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

Note 1: All channels and outputs must be configued by the carrier manager with the exception of MCH and CU channels and outputs

which are configured during Startup and/or autonomous operation,

Note 2: All measurements are made at the output connector of the Power Module. Unless otherwise specified,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 significant ripple current.
