Startup Information (using negative ON/OFF)
Scenario #1: Initial Startup From Bulk Supply
ON/OFF function enabled, converter started via application
of V
For this example, the total converter startup time (t
typically 3 ms.
Scenario #2: Initial Startup Using ON/OFF Pin
With V
ON/OFF pin. See Figure F.
For this example, the total converter startup time (t
typically 3 ms.
Scenario #3: Turn-off and Restart Using ON/OFF Pin
With V
then enabled via ON/OFF pin. See Figure G.
For the condition, (t
startup time (t
startup will be typically 3 ms after release of ON/OFF pin.

ON/OFF pin arbitrarily disabled; converter
output falls to zero; turn-on inhibit delay period
(200 ms typical) is initiated, and ON/OFF pin
action is internally inhibited.
ON/OFF pin is externally re-enabled.
Turn-on inhibit delay period ends. If ON/OFF pin
is ON, converter begins turn-on; if off, converter
awaits ON/OFF pin ON signal; see Figure F.
