Description
The 07QB-C5T Series are isolated DC/DC converters that operate from a nominal 48V source. These units will
provide up to 150W of output power from a nominal 48V input. These units are designed to be highly efficient
and low cost. Typical efficiency of 12V output at 48V 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.

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.
