0RQB-X3S11B(F)  
Isolated DC-DC Converter  
The 0RQB-X3S11B(F) is an isolated DC/DC converter that  
operates from a nominal 50/54 Vdc source. This converter is  
intended to provide isolation and step down to generate a  
regulated intermediate bus for the purpose of powering non-  
isolated Point-of-Load (POL) converters.  
This unit will provide up to 1300 W of output power from a  
nominal 50/54 Vdc input.  
The output of the converter has the droop function which allow  
the modules operating in parallel with high output current  
sharing precision. This converter is provided in a 1/4 brick  
package.

9. THERMAL DERATING CURVE  
Thermal Considerations  
New high power architectures require an accurate thermal design. Design engineers have to optimize the module working  
conditions and ensure reliable operation. Convection cooling is the common mode to cool down the module. Heat transfer is  
dependent on a test setup and it is important to characterize the module in an environment similar to existent electronic  
applications. Reported thermal data reflects real operating conditions because the values are physically measured in a wind  
tunnel.  
Thermal Test Setup  
A module in electronic cards is typically located in a busy area without relevant space around it.  
To simulate a real condition and avoid turbulence we add a cover with defined dimensions.  
The distance has to be 6.35mm (0.25”inch) from the top of the module and 6.35mm (0.25”inch) on the left and  
right side of the module.  
The values reflect most of the real applications and it is a common procedure in the power module market.  
Ambient temperature and airflow are measured in front of the module at the distance of 76.2mm (3”inch).

15. POWER GOOD  
1. The Power Good signal is a non-latching open-collector output that is Low during normal operation and is pulled High when any of the  
following conditions occur:  
• Over-Temperature  
• Over-Current  
• Vout is outside of the DC Output Band while Vin is within the Vin Operating Range  
• Vin is within the Vin Operating Range but the unit is not operating (to determine if 1 Unit used in a parallel configuration is not  
operating)  
• Vin is outside of the Vin Operating Range  
2. The Power Good signal is referenced to Vout(-).
