Description  
The 0RQB-C5T Series are isolated dc/dc converters that operate from a nominal 48 Vdc source. These units will  
provide up to 150 W of output power from a nominal 48 Vdc input. These units are designed to be highly efficient  
and low cost. Typical efficiency of 12 Vdc output at 48 Vdc input at full load is 93%. 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.
