Description
The 07LC-10T Series converters are isolated DC/DC c onverters that operate from a nominal 48V source. These converters provide up to 12W of output power. These units are des igned to be highly efficient and cost- effective. Features include remote on/off, short circuit prot ection, over-current protection, and output over- voltage protection. These converters are provided in a compact, industry standard package. Part Selection Output Voltage Input Voltage Max. Output Current Max.

Output Trim Equations Equations for calculating the trim resistor (in k Ω) 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.
