NON-ISOLATED DC/DC CONVERTERS
5 Vdc - 24 Vdc Input 0.9 Vdc - 3.3 Vdc/3 A Output
Non-Isolated
High Efficiency
High Power Density
Low Cost
Description
The Bel xRAH-03L1A0 modules are a series of non-isolated, step down dc/dc converters that operate from a
nominal 12 Vdc source. These converters are available in an output voltage range from 0.9 Vdc to 3.3 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 3.3 Vdc output is typically 88% at full load. Typical features include remote on/off, over current
protection and short circuit protection.

Notes:
1. Add “0” suffix at the end of the model number to indicate “Tube Packaging”, and “R” for “Reel
Packaging”, and “G” for “Tray Packaging”.
2. All part numbers above indicate RoHS 6. Change the second letter "R" to "7" for RoHS 5 part numbers.
