Description

The 07LC-25Txx0 series converters are isolated DC/DC converters that operate from a nominal 48V source.

These converters provide up to 25W of output power. These units are designed to be high efficient and very low

cost. Features include remote on/off, output adjust, short circuit protection, over current protection, over-

temperature protection, and input under voltage lockout. These converters are provided in a compact, through-

hole package that is easy to use and provides good thermal performance, and are pin-to-pin compatible with the

Emerson AG25 Series.

Output Trim Equations

Equations for calculating the trim resistor (in kΩ) given the desired adjusted voltage (Vadj) and the nominal

output voltage of the converter (Vnom) are shown below. The Trim Down resistor should be connected between

the Trim pin and Vout. The Trim Up resistor should be connected between the Trim pin and Ground. Only one of

the resistors should be used for any given application.
