11- Description of Functions
11-1 Trim Function
The primary output voltage Vo may be trimmed at -20%/
+10% via a single external trimpot or fixed resistor. The trimpot
should be connected as shown in figure hereafter. Value of
the trim resistance is given in the following table.
For other Vo1 Output value consult Factory
11-3 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.
The converter is disabled by pulling low the pin 4.
No connection or high impedance on pin 4 enables the
converter.
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.
11-4 Synchronization Function
The MGDM-26 series provide a bi-directionnal
synchronization function trough pin 4 (CONT)
to enable automatic synchronisation
between several converters. The converters
lock into the highest switching frequency if
more than one converter is used or on an
external clock for a frequency in the range
between 105% and 115% of the converter’s
free frequency.
11-2 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. Connection is described in figure herein.
