On/Off Control
The input-side, remote On/Off Control function can be ordered to operate with
+VIN
+Vcc
either logic type:
13V CIRCUIT
Positive ("P" suf?x) logic models are enabled when the On/Off pin is left
open or is pulled high (see speci?cations) with respect to the –Input as per
ON/OFF
Figure 4. Positive-logic devices are disabled when the on/off pin is pulled low
with respect to the –Input.
CONTROL
5V CIRCUIT
Negative (“N” suf?x) logic devices are off when the On/Off pin is left open
or is pulled high (see speci?cations), and on when the pin is pulled low with
respect to the –Input. See speci?cations.
Dynamic control of the remote on/off function is best accomplished with
a mechanical relay or an open-collector/open-drain drive circuit (optically
isolated if appropriate). The drive circuit should be able to sink appropriate
current (see Performance Speci?cations) when activated and withstand ap-
propriate voltage when deactivated. Applying an external voltage to pin 2 when
no input power is applied to the converter can cause permanent damage to the
converter.
