Description
The Bel xRAH-01FxxN modules are non-isolated; step down dc/dc converters that operate from a 3 V - 5.5 V
source. Output voltages are -5.0 V, -5.2 V, and -12 V. They are packaged in a compact, overmolded package
rated at 1 A, 1 A, 0.5 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% at 1 A, -5 V
output at full load.
