Description
The Bel x7AH-03Exx0 Series are part of the low cost non-isolated DC/DC power converters. The modules use a
surface mount package or vertical package for ease of layout and space savings, with a low profile of only
7.82mm. The output is closely regulated and the efficiency of 5V output module is typically 95% at full load.
Typical features include Remote On/Off, 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 (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.
