0RCY-F0S10x  
Isolated DC-DC Convert  
The 0RCY-F0S10x is an isolated DC/DC converter that operate from a  
nominal 50 V/54 V 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 500 W of output power from a nominal 50  
V/54 V 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 an 1/8 brick package.

9. POWER GOOD  
Note:  
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(-).

10. OVER CURRENT PROTECTION  
To provide protection in a fault output overload condition, the module is equipped with internal current-limiting circuitry and can endure  
current limiting for a few mili-seconds. If the overcurrent condition persists beyond a few milliseconds, the module will shut down into  
hiccup mode and restart once every 400ms. The module operates normally when the output current goes into specified range. The  
typical average output current is 5.6A during hiccup.

16. 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.

17. 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).
