Description
The Bel x7AH-03Hxx0 is part of the low cost non-isolated DC/DC power converter 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.
