13- Description of Functions (continued)
13-2 Sense Function
If the load is separated from the output by any line lenght,
some of these performance characteristics will be degraded
at the load terminals by an amount proportional to the
impedance of the load leads. Sense connections enable to
compensate the line drop at a maximum of +/-10% of output
voltage. The overvoltage protection will be activated and module
will shut down if remote sense tries to boost output voltage
above 110% of nominal output voltage. Connection is described
in figure herein.
13-3 On/Off Function
The control pin 4 (On/Off) can be used for applications requiring
On/Off operation. This may be done with an open collector
transistor, a switch, a relay or an optocoupler. Several
converters may be disabled with a single switch by connecting
all
On/Off pins together.
By releasing the On/Off function, the converter will restart
within the start up time specifications given in table section
4. For further details please consult ‘’Logic On/Off’’ application note.
13-4 Synchronization Function
An external clock with rectangular «Pull Up» signals can be
used to lock one or more converters. The external clock si-
gnal should have a frequency range from 860KHz to 940KHz,
a low level below 0,5V a high level of 4V (+/-0.5V), a rise
time of 30 ns max. and a drop time of 100ns max.
