SSQE48T25033 DC-DC Converter
36-75 VDC Input; 3.3 VDC, 25 A Output
Preliminary Data Sheet
V IN
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.
Time
Comments
ON/OFF
STATE
OFF
t 0
t 1
t 2
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
t 0
t 1 t 2
t 3
t
typically 3 ms.
Scenario #2: Initial Startup Using ON/OFF Pin
With V IN previously powered, converter started via
ON/OFF pin. See Figure F.

V INPUT at nominal value.
Arbitrary time when ON/OFF pin is enabled
(converter enabled).
End of 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 3 ms.

With V IN previously powered, converter is disabled and
then enabled via ON/OFF pin. See Figure G.
Fig. F: Startup scenario #2.
Time

Comments
V IN and V OUT are at nominal values; ON/OFF pin
ON.
ON/OFF pin arbitrarily disabled; converter
output falls to zero; turn-on inhibit delay period
V IN
t 2
(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
ON/OFF
STATE OFF
ON
V OUT
200 ms
internally enabled.
t 3
Turn-on inhibit delay period ends. If ON/OFF pin
is ON, converter begins turn-on; if off, converter
t 4
awaits ON/OFF pin ON signal; see Figure F.
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 203 ms. For (t 2 - t 1 ) > 200 ms ,
startup will be typically 3 ms after release of ON/OFF pin.
