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

should be connected to Vi– to enable the output (active low

logic, fail safe).

Converter operating:

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
