Description  
The 0RQB-C0U Series are isolated dc/dc converters that operate from a nominal 48 V source. These units will  
provide up to 100 W of output power from a nominal 48 V input. These units are designed to be highly efficient  
and low cost. Typical efficiency of 12 V output at 48 V input at full load is 91%. Features include remote on/off,  
over current protection and under-voltage lockout. These converters are provided in an industry standard  
quarter brick package.

Equations for calculating the trim resistor are shown below (Unit: kΩ). The Trim Down resistor should be  
connected between the Trim pin and Ground pin. The Trim Up resistor should be connected between the Trim  
pin and the Vout. Only one of the resistors should be used for any given application.
