MTC600 Series

5 of 19

Embedded Power for

Business-Critical Continuity

Output - All Models (continued)

Payload Power Interdependence

3.3 V must be applied before 12 V

Removal of 3.3 V also removes 12 V

and de-asserts ENABLE#

Setpoint

3.3 Vdc typical

Total Regulation Range

3.16 to 3.63 Vdc

Rated Load

8 W maximum

0.5 W / 150 mA maximum

Per Power Module

Per load channel

Minimum Load

No load

No loss of regulation

Output Rise TIme (per channel)

25 ms maximum

With 150 μF on output under test

50 mV maximum

75 mV maximum

0 to 30 MHz

0 to 100 MHz

Output Voltage Overshoot

2% maximum

Referenced to setpoint

Transient Response

3% maximum deviation

2 ms recovery time

37.5 mA loadstep @ 1 A/μs

Referenced to load current and setpoint at

onset of transient. Recovery time to within 1%

of setpoint at onset of transient

Voltage Sag

150 mV maximum

Primary PM to redundant PM transition with

max of 80 W load per output or 600 W load per

PM

Short Circuit Protection

225 mA maximum

12 ms maximum

Output to return

Channel Fault Operation

(Output to Return)

Output channel under fault is shutdown.

Both 3.3V and 12V are removed and

ENABLE# is de-asserted. 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 channels 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 5: 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 6: All measurements are made at the output connector of the Power Module. Unless otherwise specified,specs apply to all AMC,

MCH, and CU outputs.
