Board Mountable
DC-DC Converters

Edition 7/5.2000
20/20
Option -8
Extended Temperature Range
Extension of the temperature range from standard
–40...85
°C. In the upper temperature range the output
power derating below should be observed. The modules
will provide the specified output power with free air convec-
tion cooling.
Option K
Alternative Pinout
Option K configures the electrically isolated double outputs
to the alternative pinout with outputs connected in series
(Vo+/Go/Vo–) and common ground.
However instead of using units with option K, it is recom-
mended to use the standard double output units by provid-
ing the printed circuit board with an additional pin hole (for
pin 12 of double output units) connected to pin hole 13. This
will provide more design-in flexibility since by that both
pinouts may be used on the same PCB.
Option i
Inhibit
Excludes shut down and option K.
The output(s) of the converter may be enabled or disabled
by means of a logic signal (TTL, CMOS, etc.) applied to the
inhibit pin. No output voltage overshoot will occur when the
unit is turned on. If the inhibit function is not required the
inhibit pin should be connected to Vi– to enable the output
(active low logic, fail safe).
Converter operating:
–10 V...0.8 V
Converter inhibited
or open inhibit pin:

Option R
R Input and Magnetic Feedback
R specifies magnetic feedback from the output for closer
regulation of the output voltages of double output and sin-
gle output synchronous rectification units. It is especially
suited for applications where the two outputs are either
connected in parallel or in series to form one strong and
tight regulated output. It enables the adjustment of the out-
put voltages via the R-input on the secondary side by an
external resistor or an external voltage source in the range
of approximative 80...105% of
Uo nom. Option R excludes
the Trim input (see also table:
Pin allocation), option K as
well as the possibility to operate several converters with the
outputs connected in parallel.
