Description
The 0RQB-C0U Series are isolated dc/dc converters that operate from a nominal 48 Vdc source. These units
will provide up to 100 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 91%. Features include
remote on/off, over current protection and under-voltage lockout. These converters are provided in an industry
standard quarter brick package.

Output Trim Equations
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.
