Q48T30015 DC-DC Converter Data Sheet
36-75 VDC Input; 1.5 VDC @ 30A Output
Start-up Information (using negative ON/OFF)
Scenario #1: Initial Start-up From Bulk Supply
V IN
ON/OFF function enabled, converter started via application of V IN .
See Figure 7.
Time Comments
t 0 ON/OFF pin is ON; system front end power is toggled
on, V IN to converter begins to rise.
t 1 V IN crosses Under-Voltage Lockout protection circuit
threshold; converter enabled.
ON/OFF
STATE
OFF
ON
t 2
Converter begins to respond to turn-on command (con-
verter turn-on delay).
V OUT
t 3 Converter V OUT reaches 100% of nominal value.
For this example, the total converter start-up time (t 3 - t 1 ) is typically
2.5 ms.

Scenario #2: Initial Start-up Using ON/OFF Pin
With V IN previously powered, converter started via ON/OFF pin.
See Figure 8.
Time Comments
t 0 V INPUT at nominal value.
t 1 Arbitrary time when ON/OFF pin is enabled (converter
enabled).
t 2 End of converter turn-on delay.
t 3 Converter V OUT reaches 100% of nominal value.
For this example, the total converter start-up time (t 3 - t 1 ) is typically
2.5 ms.

Scenario #3: Turn-off and Restart Using ON/OFF Pin
With V IN previously powered, converter is disabled and then en-
abled via ON/OFF pin. See Figure 9.

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 (100 ms typical) is

initiated, and ON/OFF pin action is internally inhibited.
t 2
ON/OFF pin is externally re-enabled.
If (t 2 - t 1 ) ≤ 100 ms , external action of ON/OFF pin
is locked out by start-up inhibit timer.
t 3
If (t 2 - t 1 ) > 100 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 awaits

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 ) ≤ 100 ms , the total converter start-up
time (t 5 - t 2 ) is typically 102.5 ms. For (t 2 - t 1 ) > 100 ms , start-up will
be typically 2.5 ms after release of ON/OFF pin.
