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.
