Negative input voltage.
Positive input voltage. Unregulated input voltage (typically 48V) must be applied between
pin 1-2.
The converter is ON (Enable) when the voltage applied to this pin with reference to pin 1 is
lower than 1.2V (see Vien). The converter is OFF (Inhibit) for a control voltage in the range
of 8 to 18V. When the pin is unconnected the converter is OFF (Inhibit).
Case connection pin.
Synchronization pin. See figures 3, 4, 5, 6. Open when not used.
Parallel output. See figures 3, 4, 5, 6. Open when not used.
Senses the remote load high side. To be connected to pin 11,12 when remote sense is not
used.
Senses the remote load return. To be connected to pin 9,10 when remote sense is not
used. In parallel configuration, take care to connect all -S pins together (see figures 3,4,5,6).
Fixed output voltage return.
Fixed output voltage.
