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.

Notes
For -5V output, use a 680uF/6.3V
Oscon capacitor; For -12V output,
use 1000uF electrolytic capacitor &
22uF/10V ceramic at the input.
