On/Off Control
The input-side, remote On/Off Control function can be ordered to operate with
either logic type.
Positive ("P" suf?x) logic models are enabled when the on/off pin is left
open (or is pulled high, applying +2.4V to +5V with respect to –Input). Positive-
logic devices are disabled when the on/off pin is pulled low (-0.7 to 0.8V with
respect to –Input).
Negative (“N” suf?x) logic devices are off when pin is left open (or pulled

high, applying +2.4V to +5V), and on when pin is pulled low (–0.7 to +0.8V)
with respect to –Input.
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 appropriate 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.
