Description
The Bel x7AH-03C1A0 modules are a series of non-isolated, step down DC/DC converters that operate from a
nominal 3.3V source. These converters are available in a range of output voltages from 0.9V to 2.5V. It is
packaged in a compact, overmolded package rated at 3A. Optional lead forming provides a vertical mount
product for minimal footprint or a surface mount option for a very low profile. The output is closely regulated and
the efficiency for 2.5V output is typically 93% 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 (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.
