Description

The 07HB-D0T Series are isolated DC/DC converters that operate from a nominal 48V source. These units

provide up to 200W of output power from a nominal 48V input. These units are designed to be highly efficient

and low cost. Features include remote on/off, over current protection and under voltage lockout. These

converters are provided in an industry standard half-brick package.

Output Trim Equations

Equations for calculating the trim resistor (in kΩ) are shown below. 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.
