Functions and Signals
ENABLE* (pin D2)
This signal is used to enable the input power of the converter.
Connect this pin to SIGNAL_RTN (pin D1) to enable input power.
Leave open to disable input power.
INHIBIT* (pin C2)This signal is used to disable the main output of the converter.
Connect this pin to SIGNAL_RTN (pin D1) to disable the main output power.
Leave open to enable the main output power.
FAIL* (pin C3)This signal indicates the status of the outputs.
If the any of the output voltages drop below 85% ± 5% the signal will go 'high'.
In case any of the output voltages rise above 90% ± 5%, the signal will be 'low'.
Typical hysteresis for main output (example is 28 V) is 2%.
Typical hysteresis for 3.3V_AUX is 0.5%.
Signal type: Open-drain (connect an external pull-up resistor to 3.3V_AUX for voltage indication).
This signal is referenced to SIGNAL_RTN (pins D1)
HOLDUP_P/HOLDUP_N (pin LP9/LP11)
These pins are connected to the internal DC bus of the converter (the rectified input voltage).
Connect these pins to the appropriate pins of the Hold up Module to add a holdup feature to theconverter to provide a transparent ride-through during power interrupt events, IAW MIL-STD-704A-F.
