APPLICATION NOTES (cont’d):
Remote ON/OFF Operation
The remote ON/OFF pin may be left floating if
this function is not used. It is recommended to
drive this pin with an open collector
arrangement or a relay contact. When the
ON/OFF pin is pulled low with respect to the
-INPUT, the converter is placed in a low power
drain state. Do not drive this input from a logic
gate directly; there is a 100K internal pull-up
resistor to a 9 volt source.
Output TRIM
The TRIM pin may be used to adjust the
output ±5% from the nominal setting. This
function allows adjustment for voltage drops in
the system wiring, as well 5.2 volt outputs for
ECL applications. Figure 1 shows the proper
connections to use this function. A trimpot
value of 10K should be used for 5 volt
outputs. A trimpot value of 20K should be
used for 12 and 15 volt outputs. If the TRIM
function is not required the pin may be left
floating.
