The On/Off Control Pin
For normal operation, pin 5 should be left open. This pin has an internal
250kΩ pull-up resistor to +5V (or to +V
of the converters’ on/off functionality, a TTL logic high (+2.4V minimum,
+5V maximum or +V
enables the converter, and a quasi-TTL logic low (0 to +0.5V, 100μA max.)

disables the converter. Control voltages should be referenced to pins 3 and 4
(–Input). For best results, use a mechanical relay or open-collector logic.
When the converter is turned off, its input "standby" current will be approxi-
mately 100μA. Applying a voltage that is greater than V
trol pin, or applying any voltage to this pin when no input power is applied to
the converter, may cause permanent damage to the converter.
