Figure 17. External Resistor Value for Increasing Output
Voltage
With regard to the range that the output voltage can be adjusted
by the user, there are two concerns. As the output voltage is
raised it may become difficult to maintain regulation at full
power and low input voltage. As the output voltage is lowered,
it may become difficult to maintain regulation at minimum
power and high input line.
Pin 4 (ST AT US)
Pin 4 is active high referenced to –SENSE (Pin 1), indicating
that the output voltage is typically within
±
5%. T he pin is
pulled both up and down by internal circuitry. Figures 18 and
19 show the typical source and sink capabilities of the status
output. Refer to the paragraphs describing Pin 3 (ADJUST ) for
effect on status trip point.

Pin 5 (V

)
Pin 5 is referenced to the input return and provides a semi-
regulated 11 V to 14 V dc voltage supply for miscellaneous
system use. T he maximum permissible current draw is 5 mA
and the voltage varies with the output load of the converter as
shown in Figure 20.

Pin 6 (INHIBIT )
Pin 6 is active low and is referenced to the input return of the
converter. Connecting it to the input return will turn the
converter off. For normal operation, the inhibit pin is inter-
nally pulled up to 12 V. Use of an open collector circuit is
recommended.
When Pin 6 is disconnected from input return, the converter
will restart in the soft-start mode. Pin 6 must be kept low for at
least 2 milliseconds to initiate a full soft start. Shorter off times
will result in a partial soft start. Figure 21 shows the input
characteristics of Pin 6.
