Figure 19. 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 both
pulled up and down by internal circuitry. Figures 20 and 21
show the typical source and sink capabilities of the status out-
put. 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 13 V to 15 V dc voltage supply for miscellaneous
system use. T he maximum permissible current draw is 5 mA
and the voltage varies with the auxiliary load as shown in Figure
22.

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 internally 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 (15 ms max before the con-
verter is fully on). Pin 6 must be kept low for at least 2 milli-
seconds to initiate a full soft start. Shorter off times will result in
a partial soft start. Figure 23 shows the input characteristics of
Pin 6.
