Description

The Bel x7AH-01FxxN modules are non-isolated, step down DC/DC converters that operate from a 3V-5.5V

source. Output voltage are -5V,-12V. They are packaged in a compact, overmolded package rated at 1A, 0.5A.

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% at 1A, -5V output at full load.
