Description
The Bel xRAH-03C1A0 modules are a series of non-isolated, step down dc/dc converters that operate from a
nominal 3.3 Vdc source. These converters are available in a range of output voltages from 0.9 Vdc to 2.5 Vdc. It
is packaged in a compact, overmolded package rated at 3 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 for 2.5 Vdc output is typically 93% at full load. Typical features include remote on/off, input under
voltage lockout, over current protection and short circuit protection.
