NON-ISOLATED DC/DC CONVERTERS
4.5V-32V Input 1.2V-5.0V/3A Output
• Non-Isolated • Remote On/Off
• High Efficiency • Input Under Voltage Lockout
• High Power Density • OCP/SCP
• Excellent Thermal Performance • Low Cost
Description
The Bel X7AH-03HXX0 is part of the low cost non-isolated DC/DC converter Power Module series. 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 of 3.3V output is typically 90% at full load. Typical features include remote on/off, input under
voltage lockout, over current protection and short circuit protection.

Notes: 1. The max Turn on Voltage threshold of the 3.3V & 5.0V output module will be relaxed to 4.9V & 8.0V
respectively.
2. The max Turn off Voltage threshold of the 3.3V output module will be relaxed to 4.5V. The 5.0V
output module does not have such function.

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.
