Feature Specifications
Unless otherwise indicated, specifications apply over all operating input voltage, resistive load, and temperature
conditions. See Feature Descriptions for additional information.
Parameter
Remote On/Off Signal Interface
(V

=V
IN, min
to V

terminal)
Negative Logic: device code suffix “1”
Logic Low = module On, Logic High = module Off
Positive Logic: No device code suffix required
Logic Low = module Off, Logic High = module On
Logic Low Specification
On/Off Thresholds:
Remote On/Off Current – Logic Low (Vin =100V)
Logic Low Voltage
Logic High Voltage – (Typ = Open Collector)
Logic High maximum allowable leakage current
(V
on/off
= 2.0V)
Maximum voltage allowed on On/Off pin

T
delay
=Time until V
O
= 10% of V
O,set
from either
application of Vin with Remote On/Off set to On
(Enable with Vin); or operation of Remote On/Off from
Off to On with Vin already applied for at least 150 milli-
seconds (Enable with on/off).
* Increased T
delay
due to startup for parallel modules.
T
rise
=Time for V

to rise from 10% to 90% of V
O,set
, For
C

when pre-bias Vo exists at startup for
parallel modules.
