Description

The Bel x7AH-01Hxx0 series are part of the low cost non-isolated DC/DC converter series. These modules use

a SMD or vertical mount package for ease of layout and space savings. The output is closely regulated and the

efficiency of 5V output is typically 90% at full load. Typical features include remote on/off, input under voltage

lockout, over current protection and short circuit protection.

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 (Vo) 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.
