Description
The Bel xRAH-07C1A0 module is a series of non-isolated, step down dc/dc power 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
(default output voltage is 1.8 Vdc). It is packaged in a compact, overmolder 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 92% at full load.
