Q48T25025 DC-DC Converter Data Sheet  
36-75 VDC Input; 2.5 VDC @ 25A Output  
VIN  
Start-up Information (using negative ON/OFF)  
Scenario #1: Initial Start-up From Bulk Supply  
ON/OFF function enabled, converter started via application of VIN.  
See Figure 7.  
ON/OFF  
STATE  
OFF  
Time  
t0  
Comments  
ON/OFF pin is ON; system front end power is toggled  
on, VIN to converter begins to rise.  
t1  
t2  
t3  
VIN crosses Under-Voltage Lockout protection circuit  
threshold; converter enabled.  
Converter begins to respond to turn-on command (con-  
verter turn-on delay).  
ON  
VOUT  
Converter VOUT reaches 100% of nominal value.  
For this example, the total converter start-up time (t3- t1) is typically  
2.5 ms.

Scenario #2: Initial Start-up Using ON/OFF Pin  
With VIN previously powered, converter started via ON/OFF pin.  
See Figure 8.

Time  
Comments  
t0  
t1  
VIN and VOUT 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.  
ON/OFF pin is externally re-enabled.  
Fig. 8: Start-up scenario #2.  
VIN  
t2  
If (t2- t1) 100 ms, external action of ON/OFF pin  
is locked out by start-up inhibit timer.  
If (t2- t1) > 100 ms, ON/OFF pin action is internally  
enabled.

STATE

t3  
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 8.  
t4  
t5  
End of converter turn-on delay.  
Converter VOUT reaches 100% of nominal value.  
VOUT  
For the condition, (t2- t1) 100 ms, the total converter start-up  
time (t5- t2) is typically 102.5 ms. For (t2- t1) > 100 ms, start-up will  
be typically 2.5 ms after release of ON/OFF pin.
