Description
The Bel x7AH-07A1A0 modules are a series of non-isolated, step down dc/dc converters that operate from a
nominal 12 V source. These converters are available in a range of output voltages from 0.9 V to 3.3 V. It is
packaged in a compact, overmolded package rated at 7 A. 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 is typically 88% for 3.3 V output at full load. Typical features include remote on/off, input under
voltage lockout, over current protection and short circuit protection.
