Q24T15050 DC-DC Converter Data Sheet  
18-36 VDC Input; 5 VDC @ 15A Output  
Protection Features  
Safety Requirements  
Input Undervoltage Lockout  
The converters meet North American and International  
safety regulatory requirements per UL60950 and EN60950.  
Basic Insulation is provided between input and output.  
Input undervoltage lockout is standard with this converter.  
The converter will shut down when the input voltage drops  
below a pre-determined voltage.  
To comply with safety agencies requirements, an input line  
fuse must be used external to the converter. A 10-A fuse is  
recommended for use with this product.  
The input voltage must be at least 17.5 V for the converter to  
turn on. Once the converter has been turned on, it will shut  
off when the input voltage drops below 15 V. This feature is  
beneficial in preventing deep discharging of batteries used in  
telecom applications.  
Electromagnetic Compatibility (EMC)  
EMC requirements must be met at the end-product system  
level, as no specific standards dedicated to EMC character-  
istics of board mounted component dc-dc converters exist.  
However, Power-One tests its converters to several system  
level standards, primary of which is the more stringent  
EN55022, Information technology equipment - Radio distur-  
bance characteristics - Limits and methods of measurement.  
Output Overcurrent Protection (OCP)  
The converter is protected against overcurrent or short cir-  
cuit conditions. Upon sensing an overcurrent condition, the  
converter will switch to constant current operation and  
thereby begin to reduce output voltage. When the output  
voltage drops below 2.5 Vdc, the converter will shut down  
(Fig. 26).  
With the addition of a simple external filter (see application  
notes), all versions of the Q24T15 converters pass the re-  
quirements of Class B conducted emissions per EN55022  
and FCC, and meet at a minimum, Class A radiated emis-  
sions per EN 55022 and Class B per FCC Title 47CFR, Part  
15-J. Please contact Power-One Applications Engineering  
for details of this testing.  
Once the converter has shut down, it will attempt to restart  
nominally every 100 ms with a 2% duty cycle (Fig 27). The  
attempted restart will continue indefinitely until the overload  
or short circuit conditions are removed or the output voltage  
rises above 2.5 Vdc.  
Output Overvoltage Protection (OVP)  
The converter will shut down if the output voltage across  
Vout(+) (Pin 8) and Vout(-) (Pin 4) exceeds the threshold of  
the OVP circuitry. The OVP circuitry contains its own refer-  
ence, independent of the output voltage regulation loop.  
Once the converter has shut down, it will attempt to restart  
every 100 ms until the OVP condition is removed.  
Overtemperature Protection (OTP)  
The converter will shut down under an overtemperature con-  
dition to protect itself from overheating caused by operation  
outside the thermal derating curves, or operation in abnor-  
mal conditions such as system fan failure. After the con-  
verter has cooled to a safe operating temperature, it will  
automatically restart.
