STARTUP INFORMATION (USING NEGATIVE ON/OFF)
Scenario #1: Initial Startup From Bulk Supply
ON/OFF function enabled, converter started via application of V IN . See Figure E.

Comments
ON/OFF pin is ON; system front-end power is toggled on, V IN to converter begins to rise.
V IN crosses undervoltage Lockout protection circuit threshold; converter enabled.
Converter begins to respond to turn-on command (converter turn-on delay).
Converter V OUT reaches 100% of nominal value.
For this example, the total converter startup time (t 3 - t 1 ) is typically 5 ms.
