Auxiliary Functions
Inhibit Function
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 converter
is turned on. If the inhibit function is not required, the inhibit pin

Adjustable Output Voltage
As a standard feature, all IMX7 and IMS7 converters offer
adjustable output voltage(s) by using a control pin. If this pin is
left open-circuit, the output voltage is set to Vo nom. The output
voltage is adjustable in the range of 75 to 105% of Vo nom.The
circuit works for single- and double-output models in a
different way. For output voltages Vo > Vo nom, the minimum
input voltage Vi min (see Electrical Input Data) increases
proportionally to Vo/Vo nom.
