Note: To protect the converter under all fault conditions, an input fuse is required. Quick-blow fuses
should be rated at 2x-3x the normal input current, time-delay fuses at 1.5x the normal input current.
Notes
Note 1:
Note 2:
Maximum capacitive load is defined as the capacitive load that will allow start up in under 1 second without damage to the converter
The RS3 series requires a minimum of 10% load on the output to maintain specified regulation. Operating under no-load conditions
will not damage these devices; however, they may not meet all listed specifications.

NC = No Connection
Pin 8 (NC*)
This pin is used internally and must have no external connection.
Pin 5 (NC)
Not connected internally.
Pin 3 (CTRL)
This pin provides an Off function which puts the converter into a low power mode. When the pin is ‘high’ the converter is OFF and when the pin is high ‘Z’ the converter is ON.
There is no allowed low state for this pin.
