SSQE48T25018 DC-DC Converter
36-75 VDC Input; 1.8 VDC, 25 A Output
Data Sheet

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.

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).
V OUT
ON
t 3 Converter V OUT reaches 100% of nominal value.
For this example, the total converter startup time (t 3 - t 1 ) is
typically 5 ms.

(200 ms typical) is initiated, and ON/OFF pin
action is internally inhibited.
ON/OFF pin is externally re-enabled.
If (t 2 - t 1 ) ≤ 200 ms , external action of
ON/OFF pin is locked out by startup inhibit
timer.
If (t 2 - t 1 ) > 200 ms , ON/OFF pin action is
internally enabled.
Turn-on inhibit delay period ends. If ON/OFF pin
is ON, converter begins turn-on; if off, converter

t 4 End of converter turn-on delay.
t 5 Converter V OUT reaches 100% of nominal value.
For the condition, (t 2 - t 1 ) ≤ 200 ms , the total converter
startup time (t 5 - t 2 ) is typically 205 ms. For (t 2 - t 1 ) > 200 ms ,
startup will be typically 5 ms after release of ON/OFF pin.
